8051 MCU
12T/6T 8051 MCU
*
87 SERIES
MG87E(L)52
  • * 80C51 Central Processing Unit
  • * 8KB On-Chip program memory for program ROM, ISP ROM & IAP zone.
  • * ISP capability; optional 0.5K/1KB/1.5K~3.5KB ISP memory shared with 8KB flash memory.
  • * IAP capability; program controlled IAP memory size shared with 8KB flash memory.
  • * On-Chip 256 bytes scratch-pad RAM. Also, the MCU can address up to 64K bytes external memory.
  • * MOVC-disabling, encrypting, and locking flash memory realize security mechanism.
  • * Three 16-bits timer/counter, Timer2 is an up/down counter with programmable clock output on P1.0
  • * Eight sources, four-level-priority interrupt capability
  • * Enhanced UART, provides frame-error detection and hardware address-recognition
  • * Dual DPTR for fast-accessing of data memory
  • * 15 bits Watch-Dog-Timer with 8-bits pre-scaler, one-time enabled
  • * Low EMI: inhibits ALE emission
  • * Power control: Idle mode and Power-Down mode; Power-Down can be woken-up by P3.2/P3.3/P4.2/P4.3,Idle mode could be woken up by all interrupt sources.
  • * I/O port: 32+4 I/O ports:
    • *PDIP-40 has 32 I/O ports;
    • *PLCC-44 & PQFP-44 will have 36 I/O ports
  • * On-Chip flash program/data memory:
    • *The data endurance of the embedded flash gets over 20,000 times.
    • *Greater than 100 years data retention under room temperature. (at 25℃)
  • * Operating Voltage:
