PIC16LF1936T-I/SO 概要
A PIC microcontroller is a programmable system-on-a-chip combining an 8-bit RISC CPU core, non-volatile flash program memory, SRAM, EEPROM data memory, and a rich set of analog and digital peripherals in a single IC. The PIC16LF1936 belongs to Microchip's enhanced mid-range family, sitting in the hierarchy PIC16LF1936 -> PIC16F1936 family -> PIC16 8-bit MCU family -> PIC microcontroller -> microcontroller -> embedded computing. The 'LF' prefix denotes the low-voltage F-process variant that supports the industry's broadest operating voltage range and the nanoWatt XLP technology.
Key features include 14KB flash program memory (8K x 14 words), 512B SRAM, 256B EEPROM, integrated LCD driver supporting up to 96 segments, 11-bit ADC with up to 17 channels, multiple timers, and nanoWatt XLP sleep currents down to 20 nA. The wide 1.8V to 5.5V VDD range allows direct connection to single-cell Li-ion, 3.3V, and 5V rails without level shifters.
The PIC16LF1936 is built on Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, two hardware stack levels for interrupt handling, and a single-cycle instruction architecture at 32 MHz. The integrated LCD driver supports static, 1/2, 1/3, and 1/4 multiplexed LCD glass with on-chip charge pump, eliminating external voltage generation. Compared with the PIC16F1936, the LF variant trades absolute maximum VDD headroom for a much wider operating range and lower quiescent current.
Typical applications include battery-powered consumer devices, metering and instrumentation with LCD readout, white goods and appliance control, sensor signal conditioning nodes, and IoT edge nodes with segmented LCD displays. Its low sleep current also makes it well suited to remote controls and energy-harvesting wireless sensor nodes.
When designing with this part, route the ICSPCLK/ICSPDAT lines to a dedicated programming header for in-circuit serial programming and place a 100 nF decoupling capacitor within 5 mm of each VDD/VDDCORE pin pair to meet the datasheet's noise budget. Use the on-board MCLR internal pull-up option to free the MCLR pin as an input when no external reset is required.

設計ノート
Place a 100 nF decoupling capacitor within 5 mm of each VDD pin and a single 10 uF bulk capacitor on the supply rail. The PIC16LF1936 has multiple VSS/VDD pairs on the 28-pin SOIC; bypassing each VDD independently minimizes MCU supply-noise coupling into the analog ADC measurements.
The PIC16LF1936 differs from the PIC16F1936 in voltage-class ratings and XLP behavior. When migrating from F to LF, verify that the LF datasheet's VDD min at 32 MHz (3.0 V) is met by your supply. Also ensure that the LF sleep current specification (per nanoWatt XLP datasheet) is read from the LF document, not the F one.
Route the ICSPCLK and ICSPDAT signals (RB6/RB7) to a 6-pin in-circuit serial programming header with a 4.7 kohm pull-up on MCLR. Keep the ICSP traces short and isolated from high-current switching nodes. The RB6/RB7 pins default to ICD functions after reset, so any user application driving RB6/RB7 must yield during programming per the Microchip datasheet.
