1-T 80C51 Central Processing Unit- MG82FE(L)308 with 8K 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 6.5KB(MG82FE(L)308) 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 8 channel PWM output on P2.
- 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.
- 4 channel I/O selection on comparator Plus input.

- One-time enabled by CPU or power-on
- Maximum 45 GPIOs in LQFP-48 pin package.
- P0, P1, P2, P3, P4, P5 can be configured to quasi-bidirectional, push-pull output, open-drain output and input only.
- P6 serve quasi-bidirectional mode only.
- P4.0 and P4.1 are configured to quasi-bidirectional in default.
- Power control: idle mode and power-down mode.
- All interrupts and 16 GPIOs can wake up IDLE mode.
