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

C bus.

The CAT1021 and CAT1023 provide a precision V

sense circuit and two open drain outputs: one (RESET)

¯¯¯¯¯¯

drives high and the other (RESET) drives low whenever

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, ¯¯¯, 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

sense circuit that prevents writes to memory

whenever V

falls below the reset threshold or until V

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 3 x 3mm.
