Features of Product|

    Performance
  • high performance 8-bit CPU, compatible with 8051
  • CPU operating clock can be switched between internal oscillator and external clock.
  • 1 instruction = 1 to 3 machine cycle, 1 instruction cycle = 4 clock（typical）
    Resources
  • Memory:
    • FLASH 144k Bytes (512 BPS)
    • RAM 3k Bytes + 256 Bytes
    • OTP 200 Bytes
    • SN 8 Bytes
  • FLASH features
    • Support Sector Erase and Byte Program (512 Bytes per Sector)
    • Bit value: 1 after erasing, 0 after programming to be 0
    • Hardware Erase Verification
  • FLASH flexible to be program or data memory
    • Support CODE Bank and XDATA Bank to surmount the 64 kB limit
  • DES: DES and Tripple DES
  • CRC:16-bit CRC-CCITT
