PIC18F67J93-I/PT 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (FLASH), data memory (RAM), and a rich set of peripherals such as timers, ADC, communication interfaces, and I/O. The PIC18F67J93 sits inside Microchip's PIC18 hierarchy: PIC18 -> 8-bit PIC -> RISC microcontroller -> embedded MCU -> semiconductor. Its 64-pin TQFP package and 48 MHz core make it suitable for human-machine interface (HMI) designs where segment LCDs and analog measurement are co-located on the same board.
Key features include an integrated segment LCD driver (up to 4 common x 48 segment typical configurations), 12-bit A/D converter with 12 channels, 51 digital I/O pins, multiple serial interfaces (UART, SPI, I2C), and nanoWatt XLP power management for battery-aware applications. The wide 2.0V to 3.6V operating range supports both 2.5V and 3.3V regulated rails, and internal oscillator options reduce external component count.
Technical depth: the device uses an enhanced Harvard architecture with separate program and data buses, 16-bit instructions, and an 8-level hardware stack. The 12-bit ADC supports up to 12 channels of analog input, and the segment LCD controller directly drives glass with selectable bias and contrast via software, eliminating external LCD driver ICs.
Typical applications include handheld meters, thermostats, home security panels, portable medical devices, and utility metering products. The integrated segment LCD makes it especially valuable in any cost-sensitive product that must display numeric or alphanumeric data without a TFT.
Design consideration: ensure your PCB layout places the segment LCD traces in a tight, balanced routing pattern and provides adequate decoupling (typically 100 nF plus 10 uF bulk) near the VDD/VSS pins. Watch the absolute maximum VDD of 3.6V - this part is NOT 5V tolerant on I/O.
This page synthesizes distributor pricing, drop-in pin-compatible alternatives in the same 64-TQFP footprint, and practical design notes not found in the manufacturer datasheet alone, supporting both new designs and obsolescence-risk mitigation for PIC18F67J93-I/PT.

典型应用
PIC18F67J93-I/PT 适用于 6 应用s: Handheld Digital Multimeters, Programmable Thermostats, Home Security Control Panels, Portable Medical Monitoring Devices, Utility Electricity/Water/Gas Meters, Industrial Sensor Transmitters.
Handheld Digital Multimeters
The PIC18F67J93-I/PT fits handheld digital multimeters because its 12-bit ADC with 12 channels delivers 4096 codes of resolution for voltage, current, and resistance measurement, while the integrated segment LCD driver directly displays measured values without external driver ICs. With 128 KB FLASH and 4 KB RAM, the firmware can hold RMS calculation, range-switching logic, and autoranging algorithms. The nanoWatt XLP technology enables 200+ hour battery life on three AA cells by keeping sleep current below 1 uA. Place the MCU on the same PCB as the LCD glass with balanced trace routing to avoid segment ghosting.
推荐
Programmable Thermostats
For programmable thermostats the PIC18F67J93-I/PT provides the segment LCD driver needed for temperature, setpoint, and mode indicators on a custom glass display. Its 12-bit ADC reads NTC thermistors with 0.1 C resolution after linearization, while 128 KB FLASH holds weekly schedule logic, hysteresis control, and UI state machines. The 2.0-3.6 V VDD range supports 2x AA battery operation with the nanoWatt XLP sleep modes. The 64-TQFP (10x10 mm) footprint fits behind the LCD in a slim wall-mount enclosure with a piezo beeper for button feedback.
推荐
Home Security Control Panels
The PIC18F67J93-I/PT suits home security control panels because its 51 digital I/O pins interface with zone inputs, siren drivers, keypad matrix, and LCD status display. The integrated segment LCD driver shows zone status and alarm events without external driver hardware, while UART and SPI connect to wireless modules (Sub-GHz or Wi-Fi). With 128 KB FLASH the firmware holds event logging, user code storage, and communication protocols. The industrial -40C to +85C temperature range supports unheated garage and basement installations.
推荐
Portable Medical Monitoring Devices
Portable medical devices such as pulse oximeters and glucose meters benefit from the PIC18F67J93-I/PT 12-bit ADC for precise SpO2 and biosensor measurement, while the integrated LCD displays readings and trend graphs. The nanoWatt XLP modes extend battery life on coin cells or Li-ion packs, critical for patient mobility. 4 KB RAM holds short-term trend buffers and 128 KB FLASH stores calibration tables and UI strings. The PIC18 deterministic interrupt latency is well-suited for real-time biosignal sampling.
推荐
Utility Electricity/Water/Gas Meters
Utility metering products like electricity, water, and gas meters rely on the PIC18F67J93-I/PT for its segment LCD display showing consumption, tariff, and diagnostics. The 12-bit ADC accurately measures CT or shunt current sensors in electricity meters, while pulse counters handle water and gas meter reed-switch inputs. nanoWatt XLP and 2.0-3.6 V VDD support 10+ year battery life on a single lithium cell. The 64-TQFP fits the meter base with the LCD on the front cover connected via FPC.
推荐
Industrial Sensor Transmitters
Industrial 4-20 mA sensor transmitters use the PIC18F67J93-I/PT for its 12-bit ADC and segment LCD showing process variables in the field. UART and I2C connect to digital sensors (temperature, pressure, flow), while PWM outputs drive the 4-20 mA current loop DAC. The -40C to +85C industrial temperature range supports outdoor and factory-floor installations. 128 KB FLASH holds HART or IO-Link protocol stacks and calibration data in non-volatile memory.

设计说明
PIC18F67J93-I/PT operates from 2.0 V to 3.6 V on VDD and is NOT 5 V tolerant on any I/O pin. Use a level shifter (e.g., resistive divider or dedicated translator) when interfacing with 5 V peripherals such as legacy UART sensors. Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD/VSS pair, plus a 10 uF bulk capacitor near the MCU. The nanoWatt XLP sleep modes drop quiescent current below 1 uA but require all ADC and timers to be disabled before entry to achieve the lowest power.
Route segment LCD traces in balanced, equal-length pairs to prevent ghosting and uneven contrast on the glass. Keep LCD traces away from switching DC-DC converter nodes and clock signals to avoid injected display noise. The exposed thermal pad on the 64-TQFP should be soldered to a copper pour connected to VSS for mechanical stability and thermal dissipation; the pad is electrically floating on this part but improves thermal performance under high CPU load.
Common pitfalls: (1) Do not exceed the absolute maximum VDD of 3.6 V - this is the most frequent cause of MCU damage during bring-up. (2) Configure all unused I/O pins as outputs driving low (not inputs floating) to minimize current leakage in sleep mode. (3) The 12-bit ADC requires the AVDD pin be connected even if ADC is unused; floating AVDD causes erratic ADC readings. (4) Programming requires ICSP pins (PGECx/PGEDx) and a 10 kohm pull-up on MCLR; omitting the pull-up causes intermittent reset behavior. Estimated: input leakage typically below 50 nA per pin in sleep mode.
