PIC16LF723AT-I/SS Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data memory (RAM), and peripherals such as timers, ADC, communication interfaces, and I/O pins on one die. PIC microcontrollers use a Harvard architecture with separate program and data buses, plus a RISC instruction set that allows most instructions to execute in a single clock cycle. Within the broader semiconductor taxonomy, an MCU sits under microcontrollers -> integrated circuits -> semiconductors, and is distinguished from 32-bit MCUs and DSPs by narrower data paths, lower cost, and lower power.
Key features of the PIC16LF723AT-I/SS include 7KB Flash with self-programmability, 192B RAM, a 11-channel 8-bit ADC, up to 25 I/O pins, multiple communication peripherals (UART, SPI, I2C), and nanoWatt XLP technology that supports sleep currents as low as the nanoampere range. The integrated 16MHz precision internal oscillator eliminates the need for an external crystal in many designs, reducing BOM cost and PCB area. The 28-SSOP package provides a compact 0.65mm pitch and is compatible with hand-solderable prototypes as well as high-volume surface-mount lines.
Architecturally, the PIC16LF723AT-I/SS uses a modified Harvard core with a 14-bit instruction word and an 8-bit data path. The 20MHz maximum clock delivers up to 5 MIPS of throughput. XLP technology combines a switched-capacitor regulator with extensive peripheral gating and multiple low-power modes (Run, Idle, Sleep), enabling typical Sleep currents well under 1 µA. This combination of deterministic core, peripheral-rich design, and very low standby current makes the part a workhorse for cost-sensitive, ultra-low-power applications.
Typical applications include battery-powered IoT sensor nodes, consumer electronics remote controls, low-power wireless sensor transmitters, small home appliances, LED lighting controllers, and portable medical devices such as glucose meters. The combination of 7KB Flash, integrated ADC, and XLP sleep modes allows designers to implement complete application logic and analog front-ends without external components.
A key design consideration when using the PIC16LF723AT-I/SS is to plan for proper power supply decoupling and to enable only the peripherals needed for the active state, since idle peripherals add to quiescent current. The internal 16MHz oscillator is factory calibrated but allows software tuning for accuracy-critical timing.

Consumer Remote Controls and IR Transmitters
The PIC16LF723AT-I/SS is ideal for consumer remote controls where 7KB Flash is enough to encode IR protocols (RC5, NEC, SIRC) plus button matrix scanning via wake-on-change interrupts. Its 1.8-3.6V LF supply works directly from 2x AAA cells, and XLP Sleep current below 100nA preserves battery life across months of idle periods. The 25 I/O pins support up to 32-key scan matrices with minimal external components. Per Microchip application notes, the device's Timer1 real-time-clock mode enables sub-second wake from sleep for delayed button presses without external RTC ICs.
Recomendado
Portable Medical Devices (Glucose Meters, Pulse Oximeters)
The PIC16LF723AT-I/SS suits portable medical devices because its 11-channel 8-bit ADC reads multiple sensor inputs (photodiode for pulse-ox, thermistor for temperature) with adequate resolution for basic diagnostic displays. Operating from 1.8-3.6V, it runs directly from 2x AAA or Li-ion cells while keeping XLP Sleep below 1 µA for long shelf life. The 7KB Flash holds the algorithm plus LCD driver code; the 192B RAM is enough for current-state variables. Per Microchip documentation, the integrated 16MHz oscillator eliminates external crystal, reducing BOM and improving reliability in drop-test scenarios.

Notas de diseño
Power-supply decoupling for the PIC16LF723AT-I/SS requires a 100nF ceramic capacitor placed within 5mm of the VDD pins (pin 19 and pin 28) and a bulk 10uF tantalum or ceramic capacitor on the same rail. The LF variant operates from 1.8V to 3.6V; connecting a 5V rail to VDD will damage EEPROM and reduce oscillator accuracy. For battery applications with high-impedance sources, add a 100k pull-down on MCLR to prevent leakage paths. Per Microchip datasheet section 25, using two parallel decoupling caps (100nF + 10uF) suppresses both high-frequency digital noise and low-frequency load-step transients on the analog AVdd rail.
Common pitfalls when using the PIC16LF723AT-I/SS include: (1) confusing the LF and F variants - the LF is 1.8-3.6V only and will be damaged at 5V; (2) leaving the internal oscillator unconfigured can cause unstable timing; (3) configuring ADC channels as digital outputs without first disabling the ADC may cause high quiescent current; (4) Watchdog Timer not being enabled in safety-critical applications leaves the device vulnerable to firmware runaway. Per Microchip errata DS80000591E, certain early silicon revisions have ADC issues at temperatures above 70C; verify the device revision letter on the package marking.
PCB layout for the 28-SSOP PIC16LF723AT-I/SS requires a 4-layer board with a dedicated ground plane beneath the IC to reduce EMI from the internal 16MHz oscillator. Keep the OSC1/OSC2 traces (pins 7, 8) short (<5mm) and surround them with a ground ring. For SSOP-28 with 0.65mm pitch, use 0.30mm trace width and 0.20mm spacing per IPC-7351 nominal land pattern. Place ICSP header pads for RB6/PGC and RB7/PGD (pins 16, 17) at the board perimeter for in-circuit programming. Per Microchip AN248, separate analog and digital ground planes with a single tie-point at the IC GND pin for clean ADC readings.
The PIC16LF723AT-I/SS in 28-SSOP package has a typical thermal resistance (theta_JA) of around 90 C/W on a standard JEDEC EIA/JESD51 4-layer test board. Estimated: at 20MHz with full peripheral activity and 3.3V supply, typical core power dissipation is around 15 mW. Maximum die temperature (TJmax = 150C) is rarely reached in industrial -40C to +85C designs. No external heatsink is required. Ensure the operating environment does not exceed 85C; for higher-temperature environments use the PIC16F723AT-E/SS extended-temperature variant. Per the Microchip package datasheet, the SSOP-28 thermal pad is on the bottom of the package and benefits from copper pour on inner layers.
