Microchip PIC16LC926-I/PT 8-Bit Microcontroller Data Sheet and Application Overview
The Microchip PIC16LC926-I/PT is a high-performance, low-power 8-bit microcontroller from Microchip Technology's extensive PIC16 family. This device is engineered with a sophisticated blend of processing capability, energy efficiency, and integrated peripherals, making it a versatile solution for a wide array of embedded control applications. Fabricated with low-power CMOS technology, it is particularly well-suited for battery-powered and portable devices where power consumption is a critical design parameter.
At the core of the PIC16LC926 lies an enhanced 8-bit RISC CPU architecture. This core features a streamlined instruction set comprising only 35 single-word instructions, enabling rapid development and exceptionally efficient code execution. All instructions are single-cycle except for program branches, which require two cycles, leading to a throughput approaching 1 MIPS per MHz. This efficiency allows designers to meet performance requirements without resorting to a higher clock frequency, thereby conserving power.
A defining characteristic of this microcontroller is its ultra-low power consumption. The "LC" designation signifies its use of advanced CMOS technology, which enables very low operating currents. The device supports multiple power-saving modes, most notably SLEEP mode, where power consumption can drop to just nanoamps, effectively preserving battery life in applications that spend significant time in a standby state. This makes it ideal for remote sensors, medical implants, and handheld instruments.
The PIC16LC926-I/PT is equipped with a rich set of integrated peripherals that minimize external component count and reduce total system cost. Key features include:
8K x 14 words of Flash Program Memory for flexible and re-programmable code storage.
368 bytes of RAM and 256 bytes of EEPROM data memory for storing critical application data and parameters.
Two versatile 8-bit timers (TMR0, TMR2) and one powerful 16-bit timer (TMR1) with prescalers.
Two Capture/Compare/PWM (CCP) modules provide critical functions for timing generation, waveform production, and motor control.
A Universal Synchronous Asynchronous Receiver Transmitter (USART) for serial communication protocols like RS-232, RS-485, and LIN.
An 8-channel, 10-bit Analog-to-Digital Converter (ADC) for interfacing with analog sensors and signals from the physical world.
A Parallel Slave Port (PSP) for easy 8-bit communication with a microprocessor bus.
Housed in a 44-pin TQFP (Thin Quad Flat Pack) package, the PIC16LC926-I/PT offers a compact footprint for space-constrained PCB designs. Its industrial temperature range (-40°C to +85°C) ensures reliable operation in environmentally challenging conditions.
