PIC16F88-E/SO 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and configurable peripherals. Within the Microchip portfolio, PIC microcontrollers form a 35-instruction RISC architecture family upward-compatible with the legacy PIC16C7x, PIC16C62xA, PIC16C5X, and PIC12Cxxx devices, and sit at the bottom of the modern 8-bit PIC16F/18F hierarchy before scaling into 16-bit dsPIC and 32-bit PIC32 families.
Key features include a 20 MHz maximum operating frequency (200 ns instruction cycle), an integrated 8 MHz internal oscillator that eliminates external crystals in many designs, a 10-bit Analog-to-Digital converter with up to 7 channels, a capture/compare/PWM module, and dual configurable serial ports - an Addressable USART plus a Synchronous Serial Port that operates as either 3-wire SPI or 2-wire I2C. The 18-pin SOIC footprint is the most common PIC16F88 package and is interchangeable across the family.
Architecturally, the PIC16F88 uses a Harvard structure with separate program and data buses, 14-bit wide Flash instructions, and a hardware stack eight levels deep. The internal 8 MHz oscillator can be calibrated in software using the OSCTUNE register, allowing ±1 percent frequency accuracy without external components. Brown-out Reset, Power-on Reset, and a Watchdog Timer with its own on-chip low-power oscillator are integrated, providing five distinct oscillator modes selectable via configuration fuses.
Typical applications include battery-powered sensor nodes, automotive body controllers (when qualified through the -Q1 automotive grade), industrial control panels, and consumer appliances where a small pin count plus rich peripherals reduce external component count. Designers also use the PIC16F88-E/SO in legacy PIC16C7x socket replacements because the peripheral set and pinout are upward-compatible.
When migrating between PIC16F87 and PIC16F88, only the enhanced CCP and the added USART capability differ - existing PCB layouts and firmware libraries transfer with minimal rework. Choose -E over -I when the end product is exposed to industrial ambient temperatures above 85 C, and pair the device with a PICkit programmer for in-circuit serial programming via the ICSP pins.

主な用途
PIC16F88-E/SO の用途: 6 件s: Battery-Powered Sensor Nodes, Industrial Control Panels, Consumer Appliance Controllers, Automotive Body Electronics (Non-Safety), Legacy PIC16C7x Socket Replacement, Hobby and Educational Robotics.
Battery-Powered Sensor Nodes
The PIC16F88-E/SO is well-suited for battery-powered wireless sensor nodes because its 2.0 V to 5.5 V supply range lets it run directly from a single lithium or two alkaline cells, while the integrated 8 MHz internal oscillator eliminates the standby current of an external crystal. The 7 KB Flash holds a small protocol stack such as Modbus RTU or a proprietary RF command set, and the 10-bit ADC with up to 7 channels can read thermistor, battery-voltage, and load-sense signals without external amplifiers. The -E extended -40 C to +125 C temperature range supports outdoor or industrial-cabinet deployments where grade -I parts would otherwise fail. Designers typically pair the MCU with a sub-GHz transceiver on the SPI bus and enter Sleep mode between transmissions, drawing microamps average current.
おすすめ
Industrial Control Panels
In factory-floor control panels, the PIC16F88-E/SO drives keypads, LED indicators, and relay coils while communicating with PLCs over the Addressable USART in RS-485 mode. The 16 I/O pins are sufficient to scan a 4x4 matrix keypad, control 8 status LEDs, and drive four opto-isolated outputs, leaving the CCP module free for PWM dimming of the panel backlight. The 200 ns instruction cycle sustains deterministic polling loops for fail-safe interlocks, and the 8 MHz internal oscillator avoids the BOM cost and reliability concerns of electromechanical resonators in high-vibration enclosures. The -E grade ensures compliance with industrial -40 C to +85 C cabinet ratings.
おすすめ
Consumer Appliance Controllers
Consumer appliances such as coffee makers, washing machines, and induction cookers use the PIC16F88-E/SO as the main controller because its small 18-SOIC footprint fits tight enclosures and its peripherals consolidate dozens of discrete components. The 10-bit ADC reads temperature, water level, and current-sense signals; the CCP module generates PWM for variable-frequency motor drives; and the SPI port connects to a character-LCD or segment-display driver. The internal 8 MHz oscillator trims BOM to a handful of passives plus the IC, and the -E grade handles kitchen-ambient temperatures up to 125 C without derating.
おすすめ
Automotive Body Electronics (Non-Safety)
For non-safety body controllers such as interior lighting, mirror adjusters, and seat heaters, the PIC16F88-E/SO is used in the standard commercial grade because the operating-temperature window up to +125 C matches the cabin environment. The Addressable USART links to a body-control LIN bus master, the ADC reads current-sense shunts, and the CCP module drives MOSFET gates for dimming and motor control. Designers targeting AEC-Q100 PPAP submission should select the -Q1 qualified equivalent from Microchip's automotive catalog instead; the standard -E part is acceptable for non-regulated automotive accessories only.
おすすめ
Legacy PIC16C7x Socket Replacement
The PIC16F88-E/SO is widely used as a modern Flash replacement for legacy PIC16C7x OTP and PIC16C62xA windowed EPROM parts that are now obsolete or EOL. The 18-pin SOIC pinout is upward-compatible with the C-series footprint, and the 35-instruction PIC16 instruction set is binary-compatible with the older C7x code, so most assembly and C programs recompile without source changes. The internal 8 MHz oscillator typically replaces the original RC oscillator network, and the on-chip EEPROM data memory eliminates external 24Cxx serial EEPROMs that some C7x designs required for configuration storage. The -E grade extends the temperature envelope well beyond the original C-series specs.
おすすめ
Hobby and Educational Robotics
Maker and education platforms use the PIC16F88-E/SO because the 18-SOIC footprint is easy to hand-solder and the on-chip peripherals - PWM, ADC, USART, SPI/I2C - expose nearly every feature an introductory embedded-systems curriculum needs. The 200 ns instruction cycle and Harvard architecture make assembly teaching straightforward, and MPLAB X IDE plus PICkit programmers are available free of charge to students. The internal 8 MHz oscillator simplifies lab builds, and the -E grade tolerates the temperature swings of workshop and outdoor classroom environments. Many robotics kits boot the part at 5 V from a USB-to-USART bridge.

設計ノート
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 14 and a bulk 10 uF tantalum or aluminum-polymer cap on the same node. In battery-powered designs, place a 1 M ohm pull-down on the MCLR pin and disable the internal weak pull-ups on unused I/O to minimise Sleep current to sub-microamp levels.
Keep the 18-SOIC trace widths at least 0.2 mm for signal lines and 0.3 mm for power. Route the ICSP lines (RB6/PGC and RB7/PGD) as short and shielded as practical - on production boards the ICSP header can remain unpopulated. The OSC1/OSC2 traces must be short and symmetric when a crystal is fitted to avoid stray capacitance that shifts the oscillator off its calibrated frequency.
Do not assume the PIC16F88-E/SO ships with the internal 8 MHz oscillator enabled - the CONFIG1 register defaults to RC_IO unless re-flashed. Always re-program the configuration fuses when migrating firmware from a PIC16F87 design so that the brown-out reset voltage and watchdog timer match the new power-rail environment. A common pitfall is configuring the I2C bus with the wrong SSPADD value, which silently garbles clock edges at higher CPU speeds.
Estimated: at 20 MHz CPU, 5 V VDD, and 100 percent peripheral-active duty cycle, the PIC16F88-E/SO draws roughly 10 mA core current plus I/O loading, which means a worst-case power dissipation near 60 mW. The 18-SOIC theta_JA of approximately 95 C/W yields a junction rise of 5 to 6 C above ambient - well within the -40 C to +125 C operating envelope and not requiring thermal copper pours.
