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 400 kHz I C bus.

The CAT1021 and CAT1023 provide a precision V^CCsense 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 5 V, 3.3 V and 3 V

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.

ORDERING INFORMATION

For Ordering Information details, see page 13.

The on−chip, 2k−bit EEPROM memory features a 16−byte page. In addition, hardware data protection is provided by a VCC

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 PDIP and surface mount 8−pin SO, 8−pin TSSOP, 8−pin TDFN and 8−pin MSOP

packages. The TDFN package thickness is 0.8 mm maximum. TDFN footprint options are 3 x 3 mm.
