Part Number : M28W320
Function : 32 MBIT (2MB X16, BOOT BLOCK) LOW VOLTAGE FLASH MEMORY
Package : TFBGA47, TSOP48 Type
Manufacturers : STMicroelectronics
Pinouts :
Description :
The M28W320 is a 32 Mbit (2 Mbit x 16) nonvolatile Flash memory that can be erased electricallyat the block level and programmed in-system on aWord-by-Word basis. These operations can beperformed using a single low voltage (2.7 to 3.6V)supply. VDDQallows to drive the I/O pin down to1.65V. An optional 12V VPPpower supply is pro-vided to speed up customer programming.
