Speedy EEPROMs have choice of interfaces

Edited by the Electronicstalk editorial team Feb 18, 2002

Catalyst Semiconductor has two new high-speed serial EEPROMs: the CAT93HC46 with a Microwire interface operates at 3MHz, and the CAT24FC32 with an I2C interface operates at 1MHz.

Catalyst Semiconductor has two new high-speed serial EEPROMs: the CAT93HC46 with a Microwire interface operates at 3MHz, and the CAT24FC32 with an I2C interface operates at 1MHz.

"System microcontrollers must perform more tasks and are now operating at higher operating frequencies", said Gary Craig, product marketing manger for Catalyst memory products.

"It is important that memory speeds do not limit processor capability.

Catalyst leads the industry with 10MHz SPI serial EEPROMs and now has added 1MHz I2C and 3MHz Microwire devices to support all major interfaces".

The CAT24FC32 is a 32Kbit, Fast Mode I2C serial EEPROM that operates at 1MHz.

Both 32byte page and byte write modes are supported.

With zero standby current, the CAT24FC32 is ideal for low voltage and battery powered systems that require high-speed operation.

The CAT93HC46 is a 1Kbit, high-speed Microwire serial EEPROM that operates at 3MHz.

The user can select a x8 or x16 memory organisation.

The CAT93HC46 and CAT24FC32 devices are offered in 8-lead DIP and 8-lead surface mount SOIC and TSSOP packages.

Commercial 0 to 70C, industrial -40 to +85C, automotive -40 to +105C, and extended automotive -40 to +125C operating temperature range devices are available.

Production volumes of the CAT93HC46 and samples of the CAT24FC32 are available now.

The CAT93HC46 is priced at $0.25 each in 1000-lot units and the CAT24FC32 is priced at $0.65 each in 1000-lot units.

Production of the CAT24FC32 is scheduled for the second quarter of 2002.
