PIC16F723-E/MV - 20MHz 8-bit MCU, 7KB Flash, nanoWatt XLP | Microchip
MPN： PIC16F723-E/MV ✓ 啟用中PIC16F723-E/MV 概覽
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and configurable peripherals on a single die. Within the broader taxonomy, the PIC16F723 belongs to Microchip's PIC16 mid-range family, which sits in the larger category of microcontrollers -> microcontrollers (MCU) -> semiconductor -> integrated circuit. Mid-range PIC16 devices use a 14-bit instruction word, 35 instructions, and 8 hardware stack levels, making them well suited for embedded control where deterministic response, low power, and small code footprint matter more than raw clock speed.
Key features that differentiate this device include its nanoWatt XLP technology, which delivers typical sleep currents in the nanoamp range and active currents under 1 mA per MIPS, enabling battery-powered designs that can run for years on a single coin cell. The 11-channel 8-bit ADC and integrated mTouch hardware simplify capacitive touch user interfaces without an external touch IC. Hardware instructions are executed in a single cycle (4 Fosc), giving the 20 MHz oscillator an effective throughput of 5 MIPS for tight control loops.
Typical applications span consumer electronics, home appliances, IoT sensor nodes, capacitive-touch keypads, battery-powered handheld instruments, and low-cost motor control. The wide 1.8-5.5 V operating range lets the same firmware run directly from a single-cell Li-ion or two AA cells. The UQFN-40 footprint also supports compact PCB layouts where board area is at a premium.
Designers should provide adequate PCB copper under the exposed pad for thermal dissipation, since the UQFN package relies on the pad for heat removal. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the supply ball, and add a bulk 1-10 uF capacitor if the load transients are large.
This page synthesizes verified distributor pricing, manufacturer datasheet data, drop-in alternatives in the same UQFN-40 package, and practical design notes not found on a single distributor page, giving engineers a single starting point for PIC16F723-E/MV evaluation, sourcing, and qualification.

典型應用
PIC16F723-E/MV 適用於 7 應用s: Capacitive Touch Keypads, Battery-Powered Sensor Hubs, Home Appliance Control Boards, Industrial Sensor Nodes, Low-Cost Motor Control (BLDC / Stepper), IoT Edge Sensor with UART Bridge, Automotive Interior Lighting Controllers.
Capacitive Touch Keypads
Why the PIC16F723-E/MV fits capacitive touch keypads: the on-chip mTouch peripheral supports up to 11 touch channels via the 11-channel 8-bit ADC and dedicated CVD hardware, while the 7 KB Flash holds slider/wheel/proximity libraries and the 20 MHz / 5 MIPS core runs scanning loops in under 200 us. How it is used: the MCU scans a matrix of touch pads, debounces, and drives I2C to the host; nanoWatt XLP keeps idle current under 1 uA so a battery-powered remote can run for years from a CR2032 cell.
推薦
Battery-Powered Sensor Hubs
Why the PIC16F723-E/MV fits battery-powered sensor hubs: nanoWatt XLP delivers sleep currents in the nA range and active currents well under 1 mA per MIPS, while the 1.8-5.5 V VDD range lets the same PCB run from a single Li-ion or 2x AA cells without a boost regulator. How it is used: the MCU wakes from sleep on an ADC threshold or timer, reads sensors over I2C using the SSP peripheral, logs to internal EEPROM (256 B), and returns to sleep; expected battery life on 2x AA exceeds 5 years for 1 reading/minute duty.
推薦
Home Appliance Control Boards
Why the PIC16F723-E/MV fits home appliance control: the -E extended temperature grade (-40 C to +125 C) survives cooker hood and washing machine environments, while 36 I/O drive relays, triac interfaces, and segment LEDs directly, and the AUSART links to a Wi-Fi or BLE module for IoT retrofit. How it is used: timers and the 11-channel ADC monitor motor current and temperature; CCP modules generate triac firing pulses at zero-cross; firmware is field-upgradable through the self-programmable Flash.
推薦
Industrial Sensor Nodes
Why the PIC16F723-E/MV fits industrial sensor nodes: the 5 MIPS core handles Modbus RTU framing on the AUSART, the 8-bit ADC with internal reference simplifies 4-20 mA loop readings, and the wide 1.8-5.5 V supply tolerates 24 V industrial rails after a simple LDO. How it is used: the MCU is placed between a 4-20 mA transmitter and a Modbus RS-485 transceiver; nanoWatt XLP allows operation from a small solar cell with supercap backup, and the 256 B EEPROM stores calibration constants.
推薦
Low-Cost Motor Control (BLDC / Stepper)
Why the PIC16F723-E/MV fits small motor control: the two CCP modules generate complementary PWM up to 20 kHz with programmable dead-band, and the comparator inputs add hardware cycle-by-cycle current limit, which is essential for BLDC and stepper drives. How it is used: one CCP drives a high-side FET, the second drives the low-side FET through a gate driver; BEMF feedback is read on the ADC and a PI loop in Flash maintains RPM setpoint over load transients.
推薦
IoT Edge Sensor with UART Bridge
Why the PIC16F723-E/MV fits UART-bridged IoT edge nodes: the AUSART and SSP give simultaneous UART-to-I2C/SPI bridging for legacy peripherals, while 36 I/O multiplex GPIO to multiple SPI sensors. How it is used: the MCU sits between a Wi-Fi/BLE module and a local sensor cluster, relaying raw ADC readings on UART commands and exposing configuration over I2C; expected typical active draw is 1.2 mA at 4 MHz with nanoWatt XLP idle at 100 nA between transactions.
推薦
Automotive Interior Lighting Controllers
Why the PIC16F723-E/MV fits automotive interior lighting: the 11-channel ADC reads RGB photo-sensors for ambient-light feedback, the CCP modules generate PWM dimming for LED strings, and AUSART links to the body-control network. How it is used: each LED channel is driven from a constant-current MOSFET, duty-cycle per CCP log; firmware over the 7 KB Flash handles fade tables and CAN-style commands bridged via UART. Note: the standard -E grade is not AEC-Q100 - for OEM automotive use migrate to a Q100-qualified PIC16 family member.

主要差異化特點

- Extended temperature grade for industrial use (對比PIC16F723A-I/MV)
設計說明
Place a 100 nF decoupling ceramic capacitor within 5 mm of every VDD/VDD2 ball, plus a single 1-10 uF bulk capacitor near the supply input. The PIC16F723-E/MV has two VDD pairs (VDD/VDD2 and VSS/VSS2) on the UQFN package - tie both pairs to the same net and route them with wide traces to share switching transients.
The UQFN-40 package dissipates heat primarily through the central exposed pad. Solder the e-pad to a 5 x 5 mm copper land connected through at least 4 thermal vias (0.3 mm drill) to the inner/inner plane. Estimated junction-to-ambient theta-JA without e-pad solder is ~80 C/W; with proper soldering it drops below 35 C/W for typical MCU workloads.
Route the 20 MHz crystal traces (OSC1/OSC2) as short, symmetric pairs with a grounded guard trace or pour, and keep them away from switching power and I/O edges. For nanoU-cap sleep operation, use the internal 31 kHz LFINTOSC as the wake source to keep average current in the nA range and avoid the high-frequency oscillator start-up penalty.
Do not exceed VDD = 5.5 V absolute max; the ADC reference voltage (VR+ pin) must be <= VDD + 0.3 V. Configure unused I/O as outputs low (never inputs floating) to minimize sleep current. Always configure the MCLR pin with the internal pull-up enabled or an external 10 kohm pull-up to VDD, otherwise spurious resets will occur in noisy environments.
