描述 Description

GENERAL DESCRIPTION
The MX29F002T/B is a 2-mega bit Flash memory organized as 256K bytes of 8 bits only. MXICs Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29F002T/B is packaged in 32-pin PDIP,PLCC and 32-pin TSOP(I). It is designed to be reprogrammed and erased in-system or in standard EPROM programmers.FEATURES

? Fast access time: 55/70/90/120ns
? Low power consumption
?? - 30mA maximum active current(5MHz)
?? - 1uA typical standby current
? Programming and erasing voltage 5V ± 10%
? Command register architecture
?? - Byte Programming (7us typical)
?? - Sector Erase (16K-Byte x1, 8K-Byte x 2, 32K-Byte x1, and 64K-Byte x 3)
? Auto Erase (chip & sector) and Auto Program
?? - Automatically erase any combination of sectors or the whole chip with Erase Suspend capability.
?? - Automatically programs and verifies data at specified address
? Erase Suspend/Erase Resume
?? - Suspends an erase operation to read data from, or program data to, a sector that is not being erased, then resumes the erase operation.
? Status Reply
?? - Data polling & Toggle bit for detection of program and erase cycle completion.
? Sector protection
?? - Hardware method to disable any combination of sectors from program or erase operations
?? - Sector protect/unprotect for 5V only system or 5V/12V system
? 100,000 minimum erase/program cycles
? Latch-up protected to 100mA from -1 to VCC+1V
? Boot Code Sector Architecture
?? - T = Top Boot Sector
?? - B = Bottom Boot Sector
? Hardware RESET pin(only for 29F002T/B)
?? - Resets internal state machine to read mode
? Low VCC write inhibit is equal to or less than 3.2V
? Package type:
?? - 32-pin PDIP
?? - 32-pin PLCC
?? - 32-pin TSOP (Type 1)
? 20 years data retention
