PIC16F723T-I/MV - 28-Pin XLP 8-Bit MCU, 7KB Flash | Microchip
MPN： PIC16F723T-I/MV ✓ 啟用中PIC16F723T-I/MV 概覽
An 8-bit microcontroller (MCU) is a compact computer-on-a-chip built around an 8-bit data path. Within the broader semiconductor taxonomy, an MCU sits below microprocessor (MPU) and above application-specific integrated circuit (ASIC); the PIC16 family in particular is a mature mid-range RISC architecture from Microchip widely used for control loops, sensor interfacing, and human-machine interface (HMI) tasks. The PIC16F723 belongs to the "F72X" subset that adds nanoWatt XLP peripherals for ultra-low-power sleep modes.
Key features of the PIC16F723T-I/MV include an enhanced mid-range 16-bit instruction set with 49 instructions, 11-channel 8-bit ADC, two 8-bit and one 16-bit timers, EUSART, MSSP (SPI/I2C), and ultra-low-power sleep currents in the nanoamp range. The 28-pin UQFN package is the same 4x4 mm land pattern shared across the family, enabling footprint-compatible migration.
The device is built on Microchip's enhanced mid-range core running up to 20 MHz at 5V, with a wide 1.8V-5.5V supply that simplifies single-cell Li-ion or 3.3V system designs. XLP technology provides Sleep currents under 20 nA typical and an integrated low-power watchdog, allowing years of operation on coin-cell batteries.
Typical applications include battery-powered sensor nodes, consumer appliances, LED lighting controllers, remote controls, and low-end industrial control. The compact UQFN package suits space-constrained handheld products where board area is at a premium.
When designing with this part, derate the maximum clock at lower VDD (16 MHz at 2.5V, 8 MHz at 1.8V). Ensure MCLR is properly tied or configured as a digital input to avoid unintentional reset.

典型應用
PIC16F723T-I/MV 適用於 6 應用s: Battery-Powered Sensor Nodes, Consumer Appliance Control, LED Lighting Controllers, Remote Controls and HMI, Industrial Control and Monitoring, Low-End Medical and Wellness Devices.
Battery-Powered Sensor Nodes
The PIC16F723T-I/MV suits wireless sensor nodes where nanoWatt XLP sleep currents under 20 nA typical extend coin-cell battery life to years. Its 1.8 V to 5.5 V supply supports single-cell Li-ion or 2x AA chemistries without boost converters, and the 11-channel 8-bit ADC handles multiple temperature, light, or humidity sensors in environmental monitors. The 7 KB Flash accommodates small RTOS-free control loops with state machines, and the 20 MHz core processes sensor filtering in real time. Pair with a 2.4 GHz transceiver module for complete IoT nodes; the low active current keeps total system consumption minimal.
推薦
Consumer Appliance Control
The PIC16F723T-I/MV is well matched to consumer appliances such as coffee makers, microwave ovens, washing machines, and air purifiers, where the 25 I/O pins drive relays, keypads, seven-segment displays, and triac interfaces. The 8-bit core executes PID-like control loops at 20 MHz with predictable latency, and the EUSART plus MSSP (SPI/I2C) interface to sensors, Wi-Fi modules, and LED drivers. Industrial temperature grade (-40 to +85 C) handles under-cabinet appliance environments. The UQFN-28 package fits compact PCBs behind displays or inside small enclosures.
推薦
LED Lighting Controllers
The PIC16F723T-I/MV drives multi-channel LED strings in architectural and decorative lighting via hardware PWM or firmware bit-banging, while the 11-channel ADC reads ambient light sensors for closed-loop dimming. NanoWatt XLP technology enables always-on occupancy sensors that wake the MCU only when motion is detected, preserving the EUP standby directives. The wide 1.8 V to 5.5 V supply simplifies designs that run from a 3.3 V regulated rail or directly from rectified mains via capacitive dropper. The 7 KB Flash holds color-mixing tables and DMX-512 style protocols for commercial fixtures.
推薦
Remote Controls and HMI
Infrared and RF remote controls benefit from the PIC16F723T-I/MV's XLP sleep mode, which allows multi-year operation on a coin cell while supporting wake-on-keypad interrupts. The MSSP peripheral drives SPI/I2C OLED displays for status feedback, and the EUSART interfaces with sub-GHz RF modules such as the Microchip MRF89XA. The 25 I/O pins scan keypads up to 5x5 matrix without additional logic. The compact UQFN-28 4x4 mm package fits inside handheld enclosures where every square millimeter matters.
推薦
Industrial Control and Monitoring
Industrial sensor hubs and small PLCs leverage the PIC16F723T-I/MV's 11-channel ADC for monitoring pressure, flow, and level transducers across 4-20 mA loops with external signal conditioning. The wide supply range survives 24 V industrial bus voltage drops after regulator stages, and the -40 to +85 C industrial temperature grade meets IEC 60068-2 environmental requirements for control cabinets. The 8-bit core executes Modbus RTU framing on the EUSART for SCADA integration, while the small UQFN package supports dense I/O boards with multiple MCUs networked together.
推薦
Low-End Medical and Wellness Devices
The PIC16F723T-I/MV powers personal wellness devices such as digital thermometers, pulse oximeters, and medication reminders, where the nanoWatt XLP technology extends battery life and the 11-channel ADC reads multiple biometric sensors. The 1.8 V minimum supply supports single-cell alkaline or coin-cell operation directly, simplifying BOM cost. The IEC 60730 Class B-ready diagnostics features in the PIC16F72X family support household medical devices, though FDA-cleared designs should select the PIC16F188xx family with formal IEC 60730 library support rather than this general-purpose F72X part.

設計說明
Estimated: at 20 MHz active and 3.3 V VDD, the PIC16F723 draws approximately 2.5 mA (active current per datasheet electrical characteristics). In Sleep with WDT disabled, XLP sleep current is typically under 20 nA, enabling multi-year battery life on a 220 mAh coin cell. Place a 100 nF decoupling capacitor within 5 mm of each VDD pin and a 10 uF bulk capacitor near the IC. For battery applications, add a low-Iq LDO such as Microchip MCP1700 to provide clean 3.3 V from a discharging Li-ion source.
The UQFN-28 (MV) package has a center exposed thermal pad on pin 29 that must be soldered to a ground plane for thermal dissipation and electrical performance. Use a 4x4 array of 0.3 mm thermal vias under the pad to stitch to the inner ground layer. Keep traces short and direct to minimize EMI on high-speed signals; for crystal traces (RA6/RA7), surround them with a ground guard ring and keep total length under 10 mm to avoid oscillator startup issues.
Do not leave MCLR floating - tie it to VDD through a 10 kohm resistor or drive it with the ICSP programmer's reset line. Avoid exceeding the maximum ICSP clock frequency during in-circuit programming; the PIC16F72X family supports up to 4 MHz ICSP clock. When using the ADC, allow adequate acquisition time by setting the TACQ register appropriately for source impedance - approximately 4 us for 10 kohm sources. Do not program the configuration bits to disable the watchdog without an explicit fallback reset strategy in firmware.
Route the ICSP signals (PGC on RB6, PGD on RB7) so that a programming header can be accessed without removing the device from the board. Avoid placing the programming header behind tall components. Keep analog and digital ground domains separated where possible, joining them at a single point near the IC's VSS pin. The MSSP peripheral shares RB4/RB3/SDA/SCL pins; ensure I2C pull-ups are sized appropriately (typically 4.7 kohm at 100 kHz, 2.2 kohm at 400 kHz).
