This datasheet describes the features of 28/40/44-pin enhanced flash microcontrollers with ECAN™ Technology, 10-Bit A/D and nanoWatt Technology
The PIC18F2585/2680/4585/4680 family are 28/40/44‑pin enhanced flash microcontrollers with ECAN™ technology, 10‑bit A/D converters, and nanoWatt power management. They support multiple power‑managed modes (Run, Idle, Sleep) and offer a wide operating voltage range of 2.0 V to 5.5 V.
The datasheet details pin diagrams for all package types, memory organization (Flash, Data EEPROM, SRAM), oscillator options, peripheral modules such as the 8×8 hardware multiplier, ECAN module, and various I/O features. Electrical characteristics, timing diagrams, and packaging information are also provided.

| Watchdog timer current | 2.1 µA |
| Flash erase/write cycles | 100,000 typical |
| Data EEPROM erase/write cycles | 1,000,000 typical |
| Memory retention | > 40 years |
| High current sink/source | 25 mA |
| Operating voltage range | 2.0 V to 5.5 V |
| Package options | 28‑pin PDIP/SOIC, 40‑pin PDIP, 44‑pin TQFP/QFN |
The devices support Run (CPU and peripherals on), Idle (CPU off, peripherals on), and Sleep (CPU and peripherals off) modes.
The Flash program memory is rated for 100,000 erase/write cycles typical.
The microcontroller can sink or source up to 25 mA.
