PIC16F88x-sự phát triển tiếp theo của PIC16F87xA

[namqn]

Được Microchip gọi là "Mid-Range Product Evolution", các chip PIC16F88x có những tính năng chính như sau:

1. Special Microcontroller Features:
Precision Internal Oscillator:
- Factory calibrated to ±1%
- Software selectable frequency range of 8 MHz to 32 kHz
- Software tunable
- Two-Speed Start-Up mode
- Fail-safe clock monitoring for critical applications
- Clock mode switching during operation for low-power operation

Power-Saving Sleep mode

Power-on Reset (POR)

Selectable Brown-out Reset (BOR) voltage

Extended Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation

In-Circuit Serial Programming™ (ICSP™) via two pins

In-Circuit Debug (ICD) via two pins

High-endurance Flash/EEPROM cell:
- 100,000 erase/write cycle enhanced Flash program memory, typical
- 1,000,000 erase/write cycle data EEPROM memory, typical
- Data EEPROM retention > 40 years

Programmable code protection

Peripheral Features:
2. Device Features:
- 1 input only pin
- 36 I/O
- High sink/source current 25 mA
- Interrupt-on-pin change option

Timers:
- TMR0: 8-bit timer/counter with 8-bit prescaler
- TMR1 enhanced: 16-bit timer/counter with prescaler, External Gate Input mode and dedicated low-power 32 kHz oscillator
- TMR2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler

Enhanced Universal Synchronous Asynchronous
Receiver Transmitter (EUSART) module:
- Supports RS-485, RS-232 and LIN compatibility
- Auto-Baud Detect
- Auto-wake-up on Start bit

Ultra Low-Power Wake-up (ULPWU)

3. Analog Features:

10-bit 14 channel Analog-to-Digital (A/D) Converter

2 Analog Comparator modules with:
- Programmable on-chip Voltage Reference
(CVREF) module (% of VDD)
- Fixed 0.6 Vref
- Comparator inputs and outputs externally accessible
- SR Latch mode

PIC16F88x đã loại bỏ PSP trong PIC16F87xA, nhưng chuyển 1 CCP thành ECCP, 1 USART thành EUSART, Timer 1 thành Enhanced Timer 1, bổ sung 6 kênh A/D, và thêm internal oscilator, so với PIC16F87xA.
