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 techno–

logy. Memory interface is via a 400 kHz I

C bus.

The CAT1025 provides a precision V

sense circuit

and two open drain outputs: one (RESET) drives high

¯¯¯¯¯¯

and the other (RESET) drives low whenever V

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

sense

¯¯¯¯¯¯

circuit, but has only a RESET output and does not

have a Write Protect input.

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, ¯¯¯, 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

sense circuit that prevents writes to memory

whenever V

falls below the reset threshold or until

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 thick-

ness is 0.8 mm maximum. TDFN footprint is 3 x 3 mm.
