Description

The AT27BV010 is a high performance, low power, low voltage 1,048,576 bit one- time programmable read only memory (OTP EPROM) organized as 128K by 8 bits. It requires only one supply in the range of 2.7V to 3.6V in normal read mode opera- tion, making it ideal for fast, portable systems using either regulated or unregulated battery power. Atmel’s innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consumption of a 3V supply. At V CC = 2.7V, any byte can be accessed in less than 70 ns. With a typical power draw of only 18 mW at 5 MHz and VCC = 3V, the AT27BV010 consumes less than one fifth the power of a standard 5V (continued) Pin Configurations Pin Name Function A0 - A16 Addresses O0 - O7 Outputs CE Chip Enable OE Output Enable PGM Program Strobe NC No Connect PLCC Top View TSOP Top View Type 1 0344E AT27BV010 3-23

EPROM. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV010 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV010 is available in industry standard JEDEC- approved one-time programmable (OTP) plastic PLCC and TSOP packages. All devices feature two-line control CE, OE) to give designers the flexibility to prevent bus contention. The AT27BV010 operating with VCC at 3.0V produces TTL level outputs that are compatible with standard TTL logic devices operating at VCC = 5.0V. At VCC = 2.7V, the part is compatible with JEDEC approved low voltage battery operation (LVBO) interface specifications. The device is also capable of standard 5-volt operation making it ideally suited for dual supply range systems or card products that are pluggable in both 3-volt and 5-volt hosts. Atmel’s AT27BV010 has additional features to ensure high quality and efficient production use. The Rapid  Pro- gramming Algorithm reduces the time required to program the part and guarantees reliable programming. Program- ming time is typically only 100 µs/byte. The Integrated Product Identification Code electronically identifies the de- vice and manufacturer. This feature is used by industry standard programming equipment to select the proper programming algorithms and voltages. The AT27BV010 programs exactly the same way as a standard 5V AT27C010 and uses the same programming equipment. Description (Continued) Switching between active and standby conditions via the Chip Enable pin may produce transient voltage excur- sions. Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in de- vice non-conformance. At a minimum, a 0.1 µF high fre- quency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the V CC and Ground terminals of the device, as close to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4.7 µF bulk electrolytic capacitor should be utilized, again connected between the V CC and Ground terminals. This capacitor should be posi- tioned as close as possible to the point where the power supply is connected to the array. System Considerations 3-24 AT27BV010

This is a stress rating only and functional operation of the device at these or any other conditions beyond those indi- cated 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 undershoot to -2.0V for pulses of less than 20 ns. Maximum out- put pin voltage is V CC + 0.75V dc which may be ex- ceeded if certain precautions are observed (consult application notes) and which may overshoot to +7.0V for pulses of less than 20 ns.

The AT27BV010 has the same Product Identification Code as the AT27C010. Both are programming compatible. Rapid Programming Algorithm A 100 µs PGM pulse width is used to program. The ad- dress is set to the first location. VCC is raised to 6.5V and VPP is raised to 13.0V. Each address is first programmed with one 100 µs PGM pulse without verification. Then a verification / reprogramming loop is executed for each ad- dress. In the event a byte fails to pass verification, up to 10 successive 100 µs pulses are applied with a verifica- tion after each pulse. If the byte fails to verify after 10 pulses have been applied, the part is considered failed. After the byte verifies properly, the next address is se- lected until all have been checked. V PP is then lowered to 5.0V and VCC to 5.0V. All bytes are read again and com- pared with the original data to determine if the device passes or fails.
