Quality Control: Learn More
The Texas Instruments TMS29F256-25JE4 is a 262,144-bit NOR flash memory device organized as 32K words by 8 bits. This asynchronous device features a maximum access time of 250ns and operates from a single 4.5V to 5.5V supply. The memory organization facilitates efficient data manipulation with a page size of 64 bytes and sector sizes of 512 bytes. It supports data polling for read operations and utilizes a CMOS technology for reduced power consumption, with a standby current of 3mA and a maximum supply current of 15mA.
The TMS29F256-25JE4 is packaged in a 28-lead ceramic dual in-line package (CDIP28), specifically a windowed DIP (WDIP) with through-hole mounting. This component is suitable for applications requiring non-volatile storage in industrial and commercial systems. The programming voltage is 5V. The operating temperature range is -40°C to +85°C.
