PIC16LF723A-I/MV Übersicht
An 8-bit microcontroller (MCU) is a programmable computing engine that integrates a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and peripherals onto a single CMOS die. Within the broader semiconductor hierarchy, an 8-bit MCU sits below 32-bit microcontrollers and above simple fixed-function logic ICs; within Microchip's taxonomy it falls under PIC16 mid-range architectures, which target low-power, deterministic, interrupt-driven embedded designs rather than high-throughput DSP workloads. The PIC16F core uses a Harvard architecture with a separate instruction and data bus, allowing simultaneous fetch and access.
Key features include 7 KB Flash (4K x 14 words), 192 bytes SRAM, hardware 8/16-bit timer resources, 10-bit ADC, USART, SPI, I2C, and an internal oscillator that calibrates to within +/- 2% across the full -40 C to +85 C industrial range. The I in the suffix -I/MV indicates the industrial temperature grade, while MV is Microchip's package designator for the 28-pin UQFN 4x4 mm with exposed thermal pad. Power is supplied from a single 1.8 V to 3.6 V rail, enabling direct battery operation.
Typical applications include low-power sensor nodes, consumer remote controls, home appliances with capacitive touch UIs, battery-powered instrumentation, and IoT end-nodes where ultra-low standby current is critical. The 28 UQFN package is also footprint-compatible with PIC16F723A, allowing board reuse across higher-voltage industrial and lower-voltage battery designs. Engineers select this part when board area is constrained and when system sleep current must remain below 100 nA to extend coin-cell life across years of operation.
When designing in this device, ensure the UQFN exposed pad is soldered to a continuous ground plane to achieve the rated thermal performance, and keep analog supply traces short to avoid ADC noise coupling. Programming is performed via In-Circuit Serial Programming (ICSP) using the MPLAB ICD 5 or PICkit 5 tool chains - no external programmer socket is required.

Designhinweise
The 28-pin UQFN (MV) exposed thermal pad MUST be soldered to a continuous ground pour on the PCB. Open or partially-soldered EPADs cause ground reference shifts that couple digital switching noise into the ADC readings. Use an array of thermal vias under the pad (typically 5-9 vias on a 0.5 mm grid) to provide both electrical ground and thermal dissipation. This is the single most common reliability issue with UQFN PIC parts.
Place a 100 nF decoupling capacitor as close as possible to each VDD pin (pins 10 and 20) and a 10 uF bulk capacitor on the supply rail. The LF family draws only microamps in sleep, but the inrush during wake-up can briefly exceed 10 mA; the bulk cap prevents supply droops that reset peripherals. For battery applications, ensure the LDO quiescent current is below the MCU sleep current (sub-100 nA achievable with MCP1700).
Keep ICSP clock (RB6) and ICSP data (RB7) traces short and isolated from sensitive analog lines - these pins carry programming signals at MHz rates during flash. RB7 doubles as the in-system programming data line, so do not place series resistors or capacitors on it. If the design uses RB6/RB7 as general I/O, ensure the ICSP connector can still access these pins even when the application is running (ICSP works in-circuit).
Do not exceed 3.6 V on VDD; the LF variant has no internal 5V tolerance. If the design uses 5V sensors, add a level translator or pick the PIC16F723A variant (1.8-5.5V). Also, the internal oscillator is factory-calibrated but drifts +/- 2% across the full industrial temperature range; for UART baud-rate-sensitive applications, validate crystal vs internal OSC requirements at temperature corners. Confirmed chip variants must be ordered with explicit thermal and voltage suffixes to avoid supply surprises.
Compliance-Informationen
RoHS compliant per Microchip product page. Industrial -40 C to +85 C temperature range. Not AEC-Q100 qualified - this is a general-purpose industrial MCU. Lead-free / matte-tin plating confirmed.
