TE28F800C3BA90 NOR flash memory IC 8Mbit Parallel 90 ns 48-TSOP
The TE28F800C3BA90 is an obsolete Intel 8M-bit parallel NOR Advanced+ boot block flash memory. This memory chip supports dual bus width switching via BYTE# pin, configurable as 1M×8 byte mode or 512K×16 word mode with a maximum 90ns read access time under 2.7V to 3.6V core supply. It accepts dual voltage programming schemes: standard 3V VPP for in-circuit firmware updates and optional 12V high VPP to accelerate mass factory programming, while offering flexible 1.65V–2.5V or 2.7V–3.6V I/O rail selection to cut overall system power draw.
Low-power design features typical 9mA active read current and 10µA standby consumption with automatic power-saving APS logic, delivering a minimum 100,000 block erase cycles and 20-year data retention without external power; a built-in 128-bit security register holds a factory-locked 64-bit unique device ID plus 64-bit user programmable OTP storage for custom hardware authentication, fully compliant with standard CFI common flash interface and Intel Advanced+ command set compatible with legacy x86 BIOS, industrial PLC controllers, wireless communication modules and medical embedded devices.
Alternative Flash IC Models
1. TE28F800C3TA90: Intel pin-compatible bottom-boot variant of TE28F800C3BA90 with identical 48-TSOP footprint, 90ns speed and 3V operating range, only differing in boot block address position for hardware requiring low-address startup firmware storage.
2. IS28F800B-90: ISSI cross-brand 8M-bit parallel boot flash with matching x8/x16 bus switching, 90ns access time and 48-TSOP packaging as cost-effective drop-in replacement for legacy industrial controller refurbishment.
3. MX29F800TC-90G: Macronix modern single 3.3V NOR flash with uniform sector architecture, same storage density and TSOP form factor, optimized for new low-voltage embedded designs replacing obsolete Intel TE series flash.
4. SST39VF800A-90-4C-NHE: SST low-cost uniform-sector parallel flash without dedicated boot blocks, suitable for simplified firmware storage systems that do not require hardware-locked boot partitions.
