PIC16F1776-E/SP - 8-Bit 32MHz 14KB Flash MCU 28-SPDIP | Microchip
The Microchip Technology PIC16F1776-E/SP is an 8-bit enhanced mid-range PIC microcontroller (MCU) from the PIC16(L)F177x family, offering 14 KB (8K x 14 words) of Flash, 1 KB of SRAM, and 128 bytes of EEPROM in a 28-pin SPDIP package. It operates at up to 32 MHz CPU clock speed (200 ns instruction cycle), supports a wide 2.3V to 5.5V supply range, and provides 25 digital I/O pins. The part integrates intelligent analog peripherals including 10-bit ADCs, 8-bit DACs, comparators, op-amps, and configurable logic cells (CLC), plus Core-independent peripherals such as PWM, CWG, NCO and Zero-Cross Detect.
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, volatile data RAM, and a rich set of on-chip peripherals. PIC microcontrollers use a Harvard RISC architecture where program and data memories are separate, enabling single-cycle instruction fetch and deterministic timing. The 'XLP' (eXtreme Low Power) designation indicates sleep currents in the nanoamp range and active currents in the microamp range, making the family suitable for battery-powered IoT, sensor, and metering designs. The MCU sits at the lowest layer of an embedded system hierarchy, controlling sensors, actuators, and communication transceivers above it.
Key features include 4x 10-bit ADC channels, 2x 10-bit DACs, 2x op-amps, 2x comparators, 4x Configurable Logic Cells (CLC), 4x PWM outputs, Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), Zero-Cross Detect (ZCD), and 2x Capture/Compare/PWM (CCP) modules. The enhanced mid-range core adds 49 instructions, 16-level hardware stack, and interrupt capability with hardware context save.
The device's peripheral integration targets lighting ballast control, switched-capacitor converters, power-supply digital feedback, motor drive, and general-purpose mixed-signal designs. Designers who previously had to glue an external op-amp, DAC, and logic gates onto an MCU can now use PIC16F1776 internal resources, reducing BOM cost and PCB area.
Typical applications include LED lighting drivers, AC/DC and DC/DC power conversion, battery chargers, DC motor control, sensor signal conditioning, and consumer/industrial control. Designers choose this part for mixed-signal analog integration and ultra-low-power sleep current in battery-powered products.
When designing with this MCU, plan the oscillator start-up time using the OST, allocate the highest-priority interrupt to the analog comparator for fast over-current protection, and verify that the CLC configuration matches the application timing diagram. The -E/SP suffix denotes the -40C to +125C extended temperature grade in SPDIP package.
