93C06/46 256 Bit/1K 5.0V CMOS Serial EEPROM FEATURES • Low power CMOS technology • 16 bit memory organization - 6 x 16 bit organization (93C06) - 64 x 16 bit organization (93C46) • Single 5 volt only operation • Self-timed ERASE and WRITE cycles • Automatic ERASE before WRITE • Power on/off data protection circuitry • 1,000,000 ERASE/WRITE cycles guaranteed • Data Retention > 200 years • 8-pin DIP or SOIC package • Available for extended temperature ranges: - Commercial: 0˚C to +70˚C - Industrial: -40˚C to +85˚C - Automotive: -40˚C to +125˚C • 2 ms program cycle time DESCRIPTION The Microchip Technology Inc. 93C06/46 family of Serial Electrically Erasable PROMs are configured in a x16 organization. Advanced CMOS technology makes these devices ideal for low-power non-volatile memory applications. The 93C06/46 is available in the standard 8-pin DIP and surface mount SOIC packages. The 93C46X comes as SOIC only. These devices offer fast (1 ms) byte write and extended (-40˚C to +125˚C) temperature operation. It is recommended that all other applications use Microchip’s 93LC46.

A LOW level deselects the device and forces it into standby mode. However, a programming cycle which is already initiated and/or in progress will be completed, regardless of the CS input signal. If CS is brought LOW during a program cycle, the device will go into standby mode as soon as the programming cycle is completed. CS must be LOW for 100 ns minimum (TCSL) between consecutive instructions. If CS is LOW, the internal control logic is held in a RESET status. 2.2 Serial Clock (CLK) The Serial Clock is used to synchronize the communication betw.
