PIC16F723AT-I/MV 概要
An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip containing a CPU, non-volatile program memory (Flash), working RAM, and a set of peripheral blocks such as timers, ADCs, comparators and communication ports. Microcontrollers belong to the broader category of embedded processors and sit one level below microprocessors in system hierarchy. The PIC16 core is a Harvard-architecture RISC design from Microchip Technology, executing most instructions in a single instruction cycle and offering deterministic interrupt response. The 'F' in PIC16F723A denotes Flash program memory, allowing in-circuit re-programming via ICSP.
Key specifications of the PIC16F723AT-I/MV include 7KB of Flash program memory, 192 bytes of RAM, 11 ADC channels at 8-bit resolution, two 8-bit timers and one 16-bit timer, an Enhanced Capture/Compare/PWM (ECCP) module, and nanoWatt XLP extreme-low-power technology. Communication peripherals include AUSART (RS-232/RS-485), MSSP (I2C/SPI), and an SR-latch. Operating voltage spans 1.8V to 5.5V across LF and F speed grades, and the device supports internal 16MHz, 8MHz, 4MHz, 2MHz, 1MHz, 500kHz, 250kHz and 31kHz oscillator modes via the INTOSC block.
The architecture combines a 14-bit instruction set with 8-bit data path, giving compact code density relative to 32-bit Cortex-M cores. The PIC16F723A family is a mid-range PIC16 device that balances peripheral count with package size, making it suitable for space-constrained designs that do not need full USB or CAN stacks. The internal oscillator eliminates external crystal components, while the integrated brown-out reset (BOR) and Power-on Reset (POR) improve system reliability. nanoWatt XLP provides sleep currents below 1 uA typical, enabling battery-powered applications.
Typical applications include automotive body and convenience modules, battery-powered sensor nodes, low-power IoT endpoints, consumer appliance control panels, and small-form-factor human-machine interface (HMI) boards. The wide 1.8V-5.5V operating range also makes the part suitable for industrial sensor interfaces and 3.3V wireless modules. For designs requiring AEC-Q100 automotive qualification, this 'I' grade -40C to +85C version delivers automotive temperature resilience and PPAP documentation support.
When designing with this MCU, consider that the UQFN EP package requires thermal vias under the exposed pad to the inner PCB ground plane for proper heat dissipation during sustained CPU activity. Programming uses Microchip's ICSP interface on PGx and PGCx pins, so layout must keep these accessible. For low-power sleep-mode operation, disable unused peripherals via firmware and verify the WDT configuration matches the desired current budget.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single reference to compare footprint-compatible options and accelerate BOM decisions for 28-pin UQFN automotive-grade designs.

設計ノート
The 28-pin UQFN EP package dissipates heat through the exposed pad at the bottom of the IC. Place a thermal land beneath the package on the top layer matching the exposed pad dimensions, and stitch at least 9 thermal vias (0.3 mm drill, 0.5 mm pitch) through to the inner ground plane. Without proper thermal connection, junction temperature can exceed 125C at sustained 20 MHz operation under automotive-grade ambient conditions, causing thermal shutdown activation and unreliable Flash writes.
Place decoupling capacitors (100 nF ceramic + 10 uF tantalum or ceramic) within 3 mm of the VDD pins (pin 10 and pin 28) to suppress switching transients during CCP PWM transitions and ADC sampling. Route the VDD/VSS star-ground topology from the IC to a single point near the regulator output. Keep ADC analog traces short and shielded from PWM digital traces to minimize digital-noise coupling into the 8-bit ADC conversion results.
Do not omit the 1 kohm pull-up on MCLR if ICSP programming is required; floating MCLR will cause random resets. Configure unused I/O pins as outputs with low level to minimize sleep current. When migrating between PIC16F723A and PIC16F1827, verify the peripheral mapping differs - firmware porting is not automatic. For automotive PPAP programs, request Microchip's IMDS entry and the latest PCN history to confirm no undisclosed silicon revisions.
Route ICSP signals (PGC/PGD on RB6/RB7) with no series resistors and keep trace length under 50 mm to ensure reliable in-circuit programming at production. Add ESD protection diodes on external-facing connectors (USB, RS-485, automotive LIN/CAN) since the PIC16F723A pins are not 5V-tolerant on analog inputs when operating above 3.6V. Use TVS diodes rated for IEC 61000-4-2 8 kV contact discharge to meet automotive EMI/ESD requirements.
