Catalyst Semiconductor Leads Industry in High Speed EEPROM Technology.Business Editors SUNNYVALE, Calif.--(BUSINESS WIRE)--Feb. 14, 2002 Catalyst Semiconductor (Nasdaq:CATS) today announced two additional high-speed serial EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. products. The CAT93HC46 with a Microwire interface operates at 3MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , and the CAT24FC32 with an I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller (TM) 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 (1) (Stateful Packet Inspection) See stateful inspection. (2) (Service Provider Interface) The programming interface for developing Windows drivers under WOSA. (TM) serial EEPROMS and now has added 1MHz I2C and 3MHz Microwire(TM) devices to support all major interfaces."

The CAT24FC32 is a 32Kbit, Fast Mode I2C serial EEPROM that operates at 1MHz. Both 32-byte page and byte write modes are supported. With zero standby current, the CAT24FC32 is ideal for low voltage Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains 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 organization.
