CAT1024, CAT1025
Supervisory Circuits with
I 2 C Serial 2k-bit CMOS
EEPROM and Manual Reset
Description
The CAT1024 and CAT1025 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 2 C bus.
The CAT1025 provides a precision V CC sense circuit and two open
drain outputs: one (RESET) drives high and the other (RESET) drives
low whenever V CC falls below the reset threshold voltage. The
CAT1025 also has a Write Protect input (WP). Write operations are
disabled if WP is connected to a logic high.
The CAT1024 also provides a precision V CC sense circuit, but has
only a RESET output and does not have a Write Protect input.
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 CAT1024 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.
The CAT1024/25 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 a 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 is
3 x 3 mm.
