DESCRIPTION
The CAT1021, CAT1022 and CAT1023 are complete memory and supervisory solutions for microcontroller- based systems. A 2k-bit serial EEPROM memory and a system power supervisor with brown-out protection are integrated together in low power CMOS technology. Memory interface is via a 400kHz I 2C bus. The CAT1021 and CAT1023 provide a precision V CC sense circuit and two open drain outputs: one (RESET) drives high and the other (RESET¯¯¯¯¯¯) drives low whenever VCC falls below the reset threshold voltage. The CAT1022 has only a RESET¯¯¯¯¯¯ output and does not have a Write Protect input. The CAT1021 also has a Write Protect input (WP). Write operations are disabled if WP is connected to a logic high. All supervisors have a 1.6 second watchdog timer circuit that resets a system to a known state if software or a hardware glitch halts or “hangs” the system. For the CAT1021 and CAT1022, the watchdog timer monitors the SDA signal. The CAT1023 has a separate watchdog timer interrupt input pin, WDI. The power supply monitor and reset circuit protect memory and system controllers during power up/down and against brownout conditions. Five reset threshold voltages support 5V, 3.3V and 3V systems. If power supply voltages are out of tolerance reset signals become active, preventing the system microcontroller, ASIC or peripherals from operating. Reset signals become inactive typically 200 ms after the supply voltage exceeds the reset threshold level. With both active high and low reset signals, interface to microcontrollers and other ICs is simple. In addition, the RESET¯¯¯¯¯¯ pin or a separate input, MR¯¯¯, can be used as an input for push- button manual reset capability. The on-chip, 2k-bit EEPROM memory features a 16-byte page. In addition, hardware data protection is provided by a V CC sense circuit that prevents writes to memory whenever VCC falls below the reset threshold or until VCC reaches the reset threshold during power up. Available packages include an 8-pin DIP and surface mount 8-pin SO, 8-pin TSSOP, 8-pin TDFN and 8-pin MSOP packages. The TDFN package thickness is 0.8mm maximum. TDFN footprint options are 3x3mm.

L Characteristics subject to change without notice PIN DESCRIPTION RESET/RESET¯¯¯¯¯¯: RESET OUTPUT (RESET CAT1021/23 Only) These are open drain pins and RESET¯¯¯¯¯¯ can be used as a manual reset trigger input. By forcing a reset condition on the pin the device will initiate and maintain a reset condition. The RESET pin must be connected through a pull-down resistor, and the RESET¯¯¯¯¯¯ pin must be connected through a pull-up resistor. SDA: SERIAL DATA ADDRESS The bidirectional serial data/address pin is used to transfer all data into and out of the device. The SDA pin is an open drain output and can be wire-ORed with other open drain or open collector outputs. SCL: SERIAL CLOCK Serial clock input. MR¯¯¯: MANUAL RESET INPUT Manual Reset input is a debounced input that can be connected to an external source for Manual Reset. Pulling the MR input low will generate a Reset condition. Reset outputs are active while MR input is low and for the reset timeout period after MR returns to high. The input has an internal pull up resistor. WP (CAT1021 Only): WRITE PROTECT INPUT When WP input is tied to V SS or left unconnected write operations to the entire ar ray are allowed. When tied to VCC, the entire array is protected. This input has an internal pull down resistor. WDI (CAT1023 Only): WATCHDOG TIMER INTERRUPT Watchdog Timer Interrupt Input is used to reset the watchdog timer. If a transition from high to low or low to high does not occur every 1.6 seconds, the RESET outputs will be driven active.

CAT1021, CAT1022, CAT1023 © 2007 Catalyst Semiconductor, Inc. 7 Doc. No. 3009 Rev. L Characteristics subject to change without notice DEVICE OPERATION Reset Controller Description The CAT1021/22/23 precision RESET controllers ensure correct system operation during brownout and power up/down conditions. Th ey are configured with open drain RESET outputs. During power-u p, the RESET outputs remain active until V CC reaches the V TH threshold and will continue driving the outputs for approximately 200ms (t PURST) after reaching VTH. After the tPURST timeout interval, the device will cease to drive t he reset outputs. At this point the reset outputs will be pulled up or down by their respective pull up/down resistors. During power-down, the RESET outputs will be active when VCC falls below V TH. The RESET¯¯¯¯¯¯ output will be valid so long as V CC is >1.0V (V RVALID). The device is designed to ignore the fast negative going V CC transient pulses (glitches). Reset output timing is shown in Figure 1. Manual Reset Operation The RESET¯¯¯¯¯¯ pin can operate as reset output and manual reset input. The input is edge triggered; that is, the RESET¯¯¯¯¯¯ input will initiate a reset timeout after detecting a high to low transition. When RESET¯¯¯¯¯¯ I/O is driven to the active state, the 200 msec timer will begin to ti me the reset interval. If external reset is shorter than 200ms, Reset outputs will remain active at least 200ms. The CAT1021/22/23 also have a separate manual reset input. Driving the MR¯¯¯ input low by connecting a pushbutton (normally open) from MR¯¯¯ pin to GND will generate a reset condition. The input has an internal pull up resistor. Reset remains asserted while MR¯¯¯ is low and for the Reset Timeout period after MR¯¯¯ input has gone high. Glitches shorter than 100ns on MR¯¯¯ input will not ge- nerate a reset pulse. No external debouncing circuits are required. Manual reset operation using MR¯¯¯ input is shown in Figure 2. Hardware Data Protection The CAT1021/22/23 supervisors have been designed to solve many of the data corruption issues that have long been associated with serial EEPROMs. Data corruption occurs when incorrect data is stored in a memory location which is assumed to hold correct data. Whenever the device is in a Reset condition, the embedded EEPROM is disabled for all operations, including write operations. If the Reset output(s) are active, in progress communications to the EEPROM are aborted and no new communications are allowed. In this condition an internal write cycle to the memory can not be started, but an in progress internal non- volatile memory write cycle can not be aborted. An internal write cycle initiated before the Reset condition can be successfully finished if there is enough time (5ms) before V CC reaches the minimum value of 2V. In addition, the CAT1021 includes a Write Protection Input which when tied to V CC will disable any write operations to the device. Watchdog Timer The Watchdog Timer provides an independent protection for microcontrollers. During a system failure, CAT1021/22/23 devices will provide a reset signal after a time-out interval of 1.6 seconds for a lack of activity. The CAT1023 is designed with the Watchdog timer feature on the WDI pin. The CAT1021 and CAT1022 monitor the SDA line. If WDI or SDA does not toggle within a 1.6 second interval, the reset condition will be generated on the reset outputs. The watchdog timer is cleared by any transition on a monitored line. As long as reset signal is asserted, the watchdog timer will not count and will stay cleared.
