Key Features
- 4 Mbit dual-width Flash supporting 256K x 16-bit or 512K x 8-bit organization for flexible system integration
- 80 ns maximum access time with auto-select command user interface for simplified programming and erase
- Bottom boot block architecture with 100,000 write/erase cycle endurance for reliable non-volatile storage
Applications
The TMS28F400AEB80CDBJL is well-suited for embedded systems requiring reliable code storage, such as industrial controllers, automotive ECUs, and networking equipment. Its dual-width organization (256K x 16 or 512K x 8) makes it adaptable for 8-bit and 16-bit microprocessor systems. The bottom boot block design is ideal for applications where the boot sector must be hardware-protected against accidental erasure.

Frequently Asked Questions
What memory organization options does the TMS28F400AEB80CDBJL support?
The TMS28F400AEB80CDBJL supports two organization modes: 256K x 16-bit for 16-bit data bus systems and 512K x 8-bit for 8-bit data bus systems. This 4 Mbit total density with dual-width flexibility allows designers to interface with a wide range of 8-bit and 16-bit microprocessors without changing the physical component.
How fast can the TMS28F400AEB80CDBJL retrieve data, and what does that mean for system timing?
The TMS28F400AEB80CDBJL has a maximum access time of 80 ns, enabling it to interface with processors operating at up to approximately 12 MHz in asynchronous mode without wait states. This 80 ns speed grade is encoded in the part number suffix, and slower variants at 90 ns or 120 ns are also available depending on system timing budget.
What is the write/erase endurance of the TMS28F400AEB80CDBJL and how does it compare to typical Flash usage?
The device is rated for 100,000 write/erase cycles per block, which is standard for NOR Flash memories. For a typical embedded application that performs a firmware update once per day, this equates to over 270 years of operation, making it well-suited for long-life industrial and automotive designs operating across -40°C to +85°C.
What package does the TMS28F400AEB80CDBJL use and what are its key physical dimensions for PCB layout?
The TMS28F400AEB80CDBJL uses a 44-pin TSOP (Thin Small Outline Package) with a JESD-30 code of R-PDSO-G44. This surface-mount package features a 0.8 mm pin pitch, enabling a compact PCB footprint suitable for space-constrained designs in embedded and portable systems.
