ATF20V8B(Q)(L)2

Description

The ATF20V8B is a high-performance CMOS (electrically- erasable) programmable logic device (PLD) that utilizes Atmel’s proven electrically-erasable Flash memory technol- ogy. Speeds down to 7.5 ns and power dissipation as low as 10 mA are offered. All speed ranges are specified over the full 5V ± 10% range for industrial temperature ranges, and 5V ± 5% for commercial temperature ranges. Several low-power options allow selection of the best solu- tion for various types of power-limited applications. Each of these options significantly r educes total system power and enhances system reliability. The ATF20V8Bs incorporate a superset of the generic architectures, which allows di rect replacement of the 20R8 family and most 24-pin combinatorial PLDs. Eight outputs are each allocated eight product terms. Three different modes of operation, configured automatically with soft- ware, allow highly complex logic functions to be realized. Absolute Maximum Ratings* Maximum Ratings” may cause permanent dam- age to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note: 1. Minimum voltage is -0.6V DC which may under- shoot to -2.0V for pulses of less than 20 ns.Maxi- mum output pin voltage is V CC + 0.75V DC which may overshoot to 7.0V for pulses of less than 20 ns.

ATF20V8B(Q)(L) Input Test Waveforms and Measurement Levels tR, tF < 5 ns (10% to 90%) Output Test Loads Commercial Note: 1. Typical values for nominal supply voltage. This parameter is only sampled and is not 100% tested. Power-up Reset The registers in the ATF20V8Bs are designed to reset dur- ing power-up. At a point delayed slightly from VCC crossing VRST, all registers will be reset to the low state. As a result, the registered output state will always be high on power-up. This feature is critical for state machine initialization. How- ever, due to the asynchronous nature of reset and the uncertainty of how V CC actually rises in the system, the fol- lowing conditions are required: 1. The V CC rise must be monotonic, 2. After reset occurs, all input and feedback setup times must be met before driving the clock pin high, and 3. The clock must remain stable during t PR. Preload of Registered Outputs The ATF16V8B’s registers are provided with circuitry to allow loading of each register with either a high or a low. This feature will simplify testing since any state can be forced into the registers to control test sequencing. A JEDEC file with preload is g enerated when a source file with vectors is compiled. Once downloaded, the JEDEC file preload sequence will be done automatically by most of the approved programmers after the programming. Electronic Signature Word There are 64 bits of programmable memory that are always available to the user, even if the device is secured. These bits can be used for user-specific data. Security Fuse Usage A single fuse is provided to prevent unauthorized copying of the ATF20V8B fuse patterns. Once programmed, fuse verify and preload are inhibited. However, the 64-bit User Signature remains accessible. The security fuse should be programmed last, as its effect is immediate. Programming/Erasing Programming/erasing is performed using standard PLD programmers.

ATF20V8B(Q)(L)6 Input and I/O Pull-ups All ATF20V8B family members have internal input and I/O pull-up resistors. Therefore, whenever inputs or I/Os are not being driven externally, they will float to V CC. This ensures that all logic array inputs are at known states. These are relatively weak active pull-ups that can easily be overdriven by TTL-compatible drivers (see input and I/O diagrams below). Input Diagram I/O Diagram Functional Logic Diagram Description The Logic Option and Functional Diagrams describe the ATF20V8B architecture. Eight configurable macrocells can be configured as a registered output, combinatorial I/O, combinatorial output, or dedicated input. The ATF20V8B can be configured in one of three different modes. Each mode makes the ATF20V8B look like a dif- ferent device. Most PLD compilers can choose the right mode automatically. The user can also force the selection by supplying the compiler with a mode selection. The deter- mining factors would be the usage of register versus com- binatorial outputs and dedicated outputs versus outputs with output enable control. The ATF20V8B universal architecture can be programmed to emulate many 24-pin PAL devices. These architectural subsets can be found in each of the configuration modes described in the following pages. The user can download the listed subset device JEDEC programming file to the PLD programmer, and the ATF20V8B can be configured to act like the chosen device. Check with your programmer manufacturer for this capability. Unused product terms are automatically disabled by the compiler to decrease power consumption. A security fuse, when programmed, protects the content of the ATF20V8B. Eight bytes (64 fuses) of User Signature are accessible to the user for purposes such as storing project name, part number, revision, or date. The User Signature is accessi- ble regardless of the state of the security fuse.

ATF20V8B(Q)(L) Note: 1. Only applicable for version 3.4 or lower. ATF20V8B Registered Mode PAL Device Emulation/PAL Replacement. The registered mode is used if one or more registers are required. Each macrocell can be configured as either a registered or com- binatorial output or I/O, or as an input. For a registered out- put or I/O, the output is enabled by the OE pin, and the register is clocked by the CL K pin. Eight product terms are allocated to the sum term. For a combinatorial output or I/O, the output enable is controlled by a product term, and seven product terms are allocated to the sum term. When the macrocell is configured as an input, the output enable is permanently disabled. Any register usage will make the compiler select this mode. The following registered devices can be emulated using this mode: 20R8 20RP8 20R6 20RP6 20R4 20RP4 Registered Mode Operation Compiler Mode Selection Registered Complex Simple Auto Select ABEL, Atmel-ABEL P20V8R P20V8C P20V8 P20V8 CUPL G20V8MS G20V8MA G20V8 G20V8A LOG/iC GAL20V8_R(1) GAL20V8_C7(1) GAL20V8_C8(1) GAL20V8 OrCAD-PLD “Registered” “Complex” “Simple” GAL20V8 PLDesigner P20V8 P20V8 P20V8 P20V8 Tango-PLD G20V8 G20V8 G20V8 G20V8

ATF20V8B(Q)(L) ATF20V8B Complex Mode PAL Device Emulation/PAL Replacement. In the complex Mode, combinatorial output and I/O functions are possible. Pins 1 and 11 are regular inputs to the array. Pins 13 through 18 have pin feedback paths back to the AND-array, which makes full I/O capabilit y possible. Pins 12 and 19 (outermost macrocells) are outputs only. They do not have input capability. In this mode, each macrocell has seven product terms going to the sum term and one product term enabling the output. Combinatorial applications with an OE requirement will make the compiler select this mode. The following devices can be emulated using this mode: 20L8 20H8 20P8 Complex Mode Operation ATF20V8B Simple Mode PAL Device Emulation/PAL Replacement. In the Simple Mode, 8 product terms are allocated to the sum term. Pins 15 and 16 (center macrocells) are permanently configured as combinatorial outputs. Other macrocells can be either inputs or combinatorial outputs with pin feedback to the AND-array. Pins 1 and 11 are regular inputs. The compiler selects this mode when all outputs are combi- natorial without OE control. The following simple PALs can be emulated using this mode: 14L8 14H8 14P8 16L6 18H6 16P6 18L4 18H4 18P4 20L2 20H2 20P2 Simple Mode Option
