Description
http://onsemi.com
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

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.

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 V
CC
falls below the reset threshold or until V
CC
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.
