Catalyst Semiconductor Embeds EEPROM Memory on Power Management ICs

SUNNYVALE, Calif., Dec. 4, 2003 -- Catalyst Semiconductor (Nasdaq:CATS) has expanded its Analog EEPROM (AE² ™) product portfolio with seven new power management supervisors with high speed, embedded I2C EEPROM. As part of Catalyst Semiconductor’s AE² ™ strategy, this new microcontroller supervisory circuit family embeds a 2kbit EEPROM memory with a full-function supervisory circuit.

"Based on customer feedback from our 16kbit devices, we found strong market demand for supervisors with lower density, on-chip, EEPROM memory. We added additional functionality in the seven new 2kbit parts in the form of auxiliary voltage monitor capability and expanded pinout options that make upgrades from a 2k EEPROM device to a 2k EEPROM with integrated supervisory capability painless. Additional products scheduled for introduction in 2004 will include 32kbit, 64kbit and 128kbit EEPROMs with supervisory functions," said Catalyst Semiconductor Product Marketing Manager Gary Craig.

CAT102X Family Features
The seven CAT102x devices are built with Catalyst Semiconductor’s high quality, CMOS EEPROM process. Memory interface is through a high-speed, 400 kHz, I2C serial bus. Supervisor threshold voltages of 4.5, 4.25, 4.00, 3.00, 2.85, 2.55 volts are available.

The CAT102x family options include a watchdog timer, dual reset output polarity, watchdog input signal monitor, auxiliary voltage monitor capability and push-button manual reset. The watchdog timer function has a 1.6 second timeout and the supervisor reset period is 200 milliseconds.

Price, Packages and Availability
The CAT102x family is offered in 8-lead DIP, SOIC, MSOP, and TSSOP packages. In addition, two versions of TDFN packages are offered that feature a 0.8mm maximum height. Prices start at $0.26 in 10,000 piece quantities.

As a package option, all devices can be ordered in halogen-free, lead-free packages. Delivery lead-time is stock to 8 weeks.
