PIC16LF723AT-I/SO - 8-bit PIC MCU, 7KB Flash, 20MHz | Microchip
MPN: PIC16LF723AT-I/SO ✓ Hoạt độngPIC16LF723AT-I/SO Tóm tắt
An 8-bit PIC microcontroller is a Harvard-architecture CMOS MCU built around a RISC instruction set, with separate program Flash and data SRAM buses that allow simultaneous instruction fetch and data access. PIC16-family parts target cost-sensitive, low-power embedded designs spanning consumer, industrial, and automotive human-machine interface; the LF sub-family targets battery and energy-harvesting products. Within Microchip's taxonomy, PIC16LF723AT-I/SO sits under microcontrollers -> MCU -> 8-bit -> RISC -> PIC16 -> XLP (extreme low power), making it a member of the nanoWatt XLP series.
Key features include 7KB (4K x 14 words) Flash program memory, 192 bytes of RAM, an internal 16 MHz oscillator with selectable 31 kHz LFINTOSC, EUSART, MSSP (SPI/I2C), 10-bit ADC with multiple channels, two capture/compare/PWM modules, two comparators, nanoWatt XLP sleep currents, and brown-out reset. The 28-pin SOIC package offers 0.3-inch body width compatible with hand-soldered prototypes and reflow production.
The device uses Microchip's enhanced mid-range 16-bit instruction word architecture with a 14-bit program word length and 35 instructions, achieving deterministic throughput and industry-standard Core Independent Peripherals that offload tasks from the CPU. Internal PLL-style oscillator flexibility supports system clock tuning without external crystals in many use cases, reducing BOM cost. The wide operating range lets one part cover battery, USB-powered, and regulated industrial rails.
Typical applications include consumer remote controls, low-power wireless sensor nodes, white-goods human-interface panels, portable medical accessories, and IoT edge nodes. The combination of 7KB Flash, EUSART for host/communication links, and 10-bit ADC covers most small-signal sensing pipelines in this class. The 28-SOIC wide-body footprint allows easy probe access during development.
When designing with this part, ensure the configuration-word settings match the intended oscillator mode and that the ADC reference voltage does not exceed VDD. Use Microchip's MPLAB X IDE plus XC8 compiler with the device-specific header for register definitions and the simulator for early validation. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the pin.

Ứng dụng tiêu biểu
PIC16LF723AT-I/SO phù hợp cho 7 Áp dụngs: Consumer Remote Control, Wireless Sensor Node Edge Controller, White Goods User Interface Panel, Battery-Powered Medical Accessory, Industrial Sensor Module, USB HID Human-Interface Device, Automotive Interior Accessory.
Consumer Remote Control
The PIC16LF723AT-I/SO suits battery-powered remote controls thanks to its nanoWatt XLP technology delivering sub-microampere sleep currents and a 16 MHz internal oscillator that avoids crystals. The 7 KB Flash and 192 bytes RAM cover IR/RF protocol stacks plus keyboard matrix scanning. With 25 I/O lines it can drive up to a 5x5 matrix with interrupts, while the 10-bit ADC monitors battery voltage for end-of-life low-battery alerts. Unlike larger Cortex-M parts, this PIC16 adds no BOM cost and reduces time-to-market for IR-remote SKUs.

Wireless Sensor Node Edge Controller
In low-power wireless sensor nodes the PIC16LF723AT-I/SO acts as the sensor-conditioning companion MCU to a sub-GHz or BLE transceiver, using its 10-bit ADC to digitize analog sensor outputs while its EUSART or MSSP talks to the radio. nanoWatt XLP sleep current below 1 uA allows the node to sleep between measurements, achieving multi-year battery life on coin cells. The 7 KB Flash absorbs small protocol stacks (e.g., custom wireless or proprietary wake-up schemes) and the 28-SOIC wide-body gives generous copper area for thermal stability. This PIC16's wide VDD range down to 1.8V covers Li-MnO2 and Li-SOCl2 chemistries directly.

White Goods User Interface Panel
The PIC16LF723AT-I/SO drives user-interface panels in white goods (washing machines, dishwashers, induction cooktops) where its 25 I/O pins handle 7-segment displays, keypads, and indicator LEDs while the 2 CCP/PWM modules generate simple tones or LED dimming. Industrial -40C to +85C rating survives under-hood thermal stress and supply ripple from AC mains after rectification. The MSSP supports either SPI displays or I2C sensor expansion as design needs evolve. Its 28-SOIC wide-body makes hand-friendly prototyping without QFN inspection rigs.

Battery-Powered Medical Accessory
In portable medical accessories such as pill reminders or single-parameter patient monitors, the PIC16LF723AT-I/SO provides the compute and AD conversion needed for low-data-rate clinical tasks while nanoWalt XLP keeps sleep current under 1 uA. The 10-bit ADC is sufficient for body-temperature thermistor reading or single-channel SpO2 front-ends, while the EUSART bridges to BLE modules. The industrial temperature grade meets IEC 60068-2-14 thermal-cycling expectations for medical accessories, and the LF variant's 1.8V VDD minimum suits single-cell silver-oxide and zinc-air chemistries. The 7 KB Flash holds microcode plus the diagnostic state-machine for FDA-style event logging.

Industrial Sensor Module
The PIC16LF723AT-I/SO drives industrial 4-20 mA sensor modules by digitizing analog front-ends with its 10-bit ADC and exposing process data over Modbus RTU on the EUSART. nanoWatt XLP enables loop-powered operation where the 4-20 mA loop itself provides auxiliary power after a Schottky drop, and the brown-out reset prevents corruption during line transients. Industrial -40C to +85C withstands cabinet thermal rise, and the 28-SOIC wide-body gives the precision needed for hand-tuning analog stages. Unlike bigger dsPIC parts, the PIC16LF723 keeps unit-cost low enough for high-volume discrete-sensor SKUs in process plants.

USB HID Human-Interface Device
The PIC16LF723AT-I/SO can implement USB HID class devices such as custom keypads or vendor-specific data-acquisition sticks by leveraging its internal 16 MHz clock for low-speed USB signaling and its 10-bit ADC for analog input channels. The MSSP provides I2C/SPI bridges to host devices while the 7 KB Flash stores HID descriptor plus scan firmware. The 28-SOIC wide-body is easy to probe during USB compliance testing, and the LF variant's low-power footprint suits bus-powered accessories that must respect the 100 mA USB suspend current ceiling. Compared to using a 32-bit MCU, this part keeps BOM cost low enough for throwaway USB peripherals.

Automotive Interior Accessory
Although non-Q1-qualified, the PIC16LF723AT-I/SO finds use in non-safety automotive interior accessories such as cup-holder lighting, ambient lighting drivers, or seat-occupancy sensor reading modules. The 10-bit ADC handles thermocouples or capacitive sensor front-ends, while the two CCP/PWM modules deliver proportional LED control with hardware-determined flicker frequencies. The industrial -40C to +85C rating covers interior cabin thermal range after cold-start; for under-hood applications upgrade to the AEC-Q100 qualified PIC16 variant. The 28-SOIC wide-body simplifies rework during prototype bring-up.

Ghi chú thiết kế
Estimated: For a 3.3 V application the LF variant's nanoWatt XLP sleep current stays below 1 uA in real-power-down mode, but VDD decoupling must include a 100 nF X7R ceramic within 5 mm of pin 16 (Vdd) plus a bulk 1 uF to ground for ADC noise suppression. Use an LDO with PSRR above 50 dB at 100 kHz for the ADC reference path if switch-mode supplies are upstream. Brown-out reset should be configured to trip at the lowest reliable VDD for the chosen clock speed.
Place ICSP test points or pads on the RB6/RB7/RA5 footprint so that PICkit 4 or MPLAB SNAP can attach to a populated board for debug. The 28-SOIC wide-body has 1.27 mm pitch pads - leave at least 0.5 mm clearance between MCLR/VPP net and high-voltage analog traces to prevent programming pulses from corrupting analog samples. Keep the ICP programming header out of the way of RF/USB sub-circuits; estimated signal-integrity risk at 1.27 mm pitch is minimal for signals under 50 MHz.
Do not leave the MCLR/VPP pin floating - tie it through a 10 kohm pull-up to VDD, or leave it unused only when the configuration bit MCLRE is cleared. Reading the configuration word is mandatory before code commit; mistakes in the oscillator selection frequently cause device lock-outs that require high-voltage VPP to recover. The ADC clock must be set so that Fosc/4 is between 1 MHz and 8 MHz - failing this can silently yield invalid ADC readings. Always validate at the bottom of the operating temperature range.
