Detailed Description

PIC16F690 is an 8-bit CMOS microcontroller from Microchip’s PIC16 family. It is designed for low power and cost-effective control tasks, with on-chip Flash program memory, SRAM, data EEPROM, and a broad set of analog and digital peripherals. Typical functions include a 10-bit ADC with multiple channels, analog comparators, EUSART for serial communication, an MSSP interface for I2C/SPI, internal oscillator options, multiple timers, watchdog, brown-out reset, and in-circuit programming/debug support. It is commonly offered in 20-pin packages and provides up to about 18 versatile I/O lines across ports A, B, and C.

Key Features

8-bit PIC16 core with 14-bit instructions (Harvard architecture)

Flash program memory, on-chip data EEPROM, and SRAM

Internal oscillator options; external crystal/clock support

10-bit ADC with multiple analog input channels

Analog comparators for signal monitoring

EUSART for asynchronous serial communication

MSSP for I2C/SPI connectivity (device configuration dependent)

Timers (e.g., Timer0, Timer1, Timer2), watchdog timer, brown-out reset

Multiple interrupt sources for responsive control

Up to ~18 general-purpose digital I/O lines (RA/RB/RC)

Very low power consumption suitable for battery-powered devices

Rich peripheral mix enables single-chip solutions for many embedded tasks

Simple development flow with MPLAB X IDE and Microchip XC8 compiler

Long-term availability and stable supply from Microchip

Multiple package options for prototyping and volume production

Packaging

Type: Available in common Microchip 20-pin options such as PDIP-20 (through-hole), SOIC-20 (surface-mount), and QFN/MLF-20 (compact surface-mount). The provided Package/Case code is 1057; use the datasheet to confirm exact mechanical details tied to this code.

Material: Molded epoxy plastic over copper leadframe (typical for PDIP/SOIC/MLF families).

Size: Standard JEDEC-compliant body outlines; refer to the datasheet mechanical drawings for exact dimensions and land patterns for each package option.

Pin configuration: 20 pins across ports A, B, C with multifunction assignments (digital I/O, analog inputs, EUSART TX/RX, I2C/SPI lines, MCLR/VPP, OSC1/OSC2, VDD/VSS). Pin functions vary by package and configuration—always verify with the datasheet.

Thermal characteristics: Typical industrial operating range of -40°C to +85°C (package and grade dependent). Thermal performance and power dissipation depend on package and PCB layout; follow datasheet derating guidelines.

Electrical properties: Typical operating voltage around 2.0–5.5 V; internal oscillator options; low sleep current; 10-bit ADC; multiple timers; interrupt-driven peripherals; maximum CPU frequency typically up to ~20 MHz (refer to datasheet for exact limits).

Lifecycle
