M39432 Datasheet PDF - STMicroelectronics

DESCRIPTION
The M39432 is a single supply voltage memory device combining Flash memory and EEPROM on a single chip. The memory is mapped in two blocks: 4 Mbit of Flash memory and 256 Kbit of EEPROM. Each block operates independently during a Write cycle: in concurrent mode, the Flash Memory can be read while the EEPROM is being written.

■Multiple Memories on a Single Chip:
– 4 Mbit Flash Memory (organised as 8 sectors)
– 256 Kbit EEPROM
– 64 Byte One Time Programmable Memory
■CONCURRENT Mode (Read Flash while
writing to EEPROM)
■WRITE, PROGRAM and ERASE Status Bits
■2.7V to 3.6V Single Supply Voltage for
PROGRAM, ERASE and READ Operations
■100 ns Access Time (Flash and EEPROM blocks)
■Low Power Consumption
–60µA Stand-by mode (maximum)
– Deep Power Down mode: 6µA (maximum), 200 nA (typical)
■Standard Flash Memory Package
■100,000 Erase/Write Cycles (minimum)
■10 Year Data Retention (minimum)
