1-T 80C51 Central Processing Unit- MG82FE(L)316 with 16K Bytes AP flash ROM
ISP memory zone as 1.5KB (Built-in Megawin standard ISP & UART COMBO ISP code with auto switching)- IAP size as 1KB(MG82FE(L)316) in default.
- User could control IAPLB register to redefine IAP size. Flexible IAP size up to 15.5KB.
- Code protection for flash memory access
- On-chip 256 bytes data RAM and on-chip 256 bytes expanded RAM.
- Dual data pointer.
- Three 16-bit timer/counters: Timer 0, Timer 1 and Timer 2.
- T0CKO on P34, T1CKO on P35 and T2CKO on P10
- X12 mode enabled for T0/T1/T2.
- PWM-Timer for PWM generator or normal 16-bit timer.
- Maximum 16 channel PWM output on P2 and P5.
- Enhanced UART
- Provides frame-error detection.
- Hardware address-recognition.
- Function swapped on P16/P17.
- Six external interrupt input: nINT0/nINT1/nINT2/nINT3/nINT4/nINT5.
- nINT0/nINT1 trigger type: Low Level or Falling Edge.
- nINT2/nINT3/nINT4/nINT5: Low Level, Falling Edge, High Level or Rising Edge.
- 13 sources, four-level-priority interrupt capability.
- Built-in analog comparator with on-chip VDD reference input.
