DESCRIPTION
The CAT130xx (see table below) are memory and
supervisory solutions for microcontroller based
systems. A CMOS serial EEPROM memory and a
system power supervisor with brown-out protection
are integrated together. Memory interface is via
Microwire serial protocol.
The CAT130xx provides a precision VCC sense circuit
with two reset output options: CMOS active low output
or CMOS active high. The RESET output is active
whenever VCC is below the reset threshold or falls
below the reset threshold voltage.
The power supply monitor and reset circuit protect
system controllers during power up/down and against
brownout conditions. Seven reset threshold voltages
support 5V, 3.3V, 3V and 2.5V 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 240ms after the supply
voltage exceeds the reset threshold level.

Note:
When the ORG pin is connected to VCC, the x16 organization is
selected. When it is connected to ground, the x8 pin is selected. If
the ORG pin is left unconnected, then an internal pullup device will
select the x16 organization.

CAT130xx
EMBEDDED EEPROM OPERATION
The CAT130xx has a nonvolatile embedded memory
intended for use with industry standard micropro–
cessors. The memory can be organized as either
registers of 16 bits or 8 bits. The CAT130xx operates
on a single power supply and will generate on chip the
high voltage required during any write operation.
The format for all instructions sent to the device is a
logical “1” start bit, a 2-bit (or 4-bit) opcode, 6-bit
(13001) / 8-bit (13004) / 9-bit (13008) / 10-bit (13016)
address (an additional bit when organized as x8) and
for write operations a 16-bit data field (8-bit for x8
organization). The instruction format is shown in
Instruction Set Table.
