  • 80C51 core
  • Selectable 12T or 6T mode
  • Maximum operating frequency: 48MHz@12T or 24MHz@6T
  • Program space: MPC89E/L51 (4KB), MPC89E/L52 (8KB), MPC89E/L53 (15KB), MPC89E/L54 (16KB), MPC89E/L58 (32KB), MPC89E/L515 (63KB)
  • ISP space size: selectable 1K/2K/4K ISP space; shared with data space for MPC89x51/52/53/54/58, shared with application space for MPC89x53/515
  • IAP space size: MPC89x51: up to 10KB, shared data space with ISP space; MPC89x52: up to 6KB, shared data space with ISP space; MPC89x53: none; MPC89x54: up to 46KB, shared data space with ISP space; MPC89x58: up to 30KB, shared data space with ISP space; MPC89x515: none. Note: to use IAP, ISP space must be set to a minimum of 1K
  • Built-in external addressing RAM (XDATA): MPC89x51/52/53 (256 Byte), MPC89x54/58/515 (1024 Byte)
  • Two-level code encryption protection
