GENERAL DESCRIPTION
The MT28C3214P2FL and MT28C3214P2NFL combination Flash and SRAM memory devices provide a compact, low-power solution for systems where PCB real estate is at a premium. The dual-bank Flash is a high-performance, high-density, nonvolatile memory device with a revolutionary architecture that can significantly improve system performance.

FEATURES
• Flexible dual-bank architecture
• Support for true concurrent operations with no latency:
   Read bank b during program bank a and vice versa
   Read bank b during erase bank a and vice versa
• Organization: 2,048K x 16 (Flash)
   256K x 16 (SRAM)
• Basic configuration:
   Flash
      Bank a (4Mb Flash for data storage)
      – Eight 4K-word parameter blocks
      – Seven 32K-word blocks
      Bank b (28Mb Flash for program storage)
