SST38VF6401B-70I/CD IC FLASH 64MBIT PARALLEL 48TFBGA Microchip Technology

 

PRODUCT DESCRIPTION

The SST38VF166 consists of three memory banks, 2 each 512K x16 bits sector mode flash EEPROM plus a 4K x16 bits word alterable E2PROM manufactured with SST’s proprietary, high performance SuperFlash Technology. The SST38VF166 erases and programs with a single power supply. The internal Erase/Program in the E2 bank is transparent to the user. The device conforms to (proposed) JEDEC standard pinouts for word-wide memories.
