The SPC560P34/SPC560P40 provides 320 KB of programmable, non-volatile, flash memory. The non-volatile memory (NVM) can be used for instruction and/or data storage. The flash memory module is interfaced to the system bus by a dedicated flash memory controller.

It supports a 32-bit data bus width at the system bus port, and a 128-bit read data interface to flash memory. The module contains four 128-bit wide prefetch buffers only in the process of recovering automobile microprocessor spc560p40l3 flash memory firmware. Prefetch buffer hits allow no-wait responses. Normal flash memory array accesses are registered and are forwarded to the system bus on the following cycle, incurring two wait-states.

The flash memory module provides the following features:

  • As much as 320 KB flash memory
    • 6 blocks (32 KB + 2×16 KB + 32 KB + 32 KB + 128 KB) code flash memory
      • 4 blocks (16 KB + 16 KB + 16 KB + 16 KB) data flash memory
      • Full Read-While-Write (RWW) capability between code flash memory and data flash memory
    • Four 128-bit wide prefetch buffers to provide single cycle in-line accesses (prefetch buffers can be configured to prefetch code or data or both)
    • Typical flash memory access time: no wait-state for buffer hits, 2 wait-states for page buffer miss at 64 MHz
    • Hardware managed flash memory writes handled by 32-bit RISC Krypton engine
    • Configurable access timing allowing use in a wide range of system frequencies
    • Multiple-mapping support and mapping-based block access timing (up to 31 additional cycles) allowing use for emulation of other memory types
    • Software programmable block program/erase restriction control
    • Erase of selected block(s)
    • Read page sizes
      • Code flash memory: 128 bits (4 words)
      • Data flash memory: 32 bits (1 word)
    • ECC with single-bit correction, double-bit detection for data integrity
      • Code flash memory: 64-bit ECC
      • Data flash memory: 32-bit ECC
    • Embedded hardware program and erase algorithm
    • Erase suspend and program abort
    • Censorship protection scheme to prevent flash memory content visibility

Hardware support for EEPROM emulation
