PIC16F627-04E/SS 概要
An 8-bit microcontroller is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals onto one silicon die. The 8-bit designation refers to the native data-path width; values are processed in 8-bit chunks. Within the broader taxonomy, the PIC16F627 sits in the microcontroller -> embedded controller -> semiconductor hierarchy, while the RISC-style Harvard architecture places it in the mid-range PIC16 family, which is a sub-class of Microchip's PIC product line.
Key features include 16 I/O pins with individual direction control, two analog comparators with programmable on-chip voltage reference, a USART module for asynchronous and synchronous serial communication, and a capture/compare/PWM (CCP) module. The device also integrates a power-on reset (POR), brown-out detect (BOD), watchdog timer (WDT) with its own on-chip RC oscillator, and programmable weak pull-ups on PORTB for direct interface to mechanical switches.
Architecturally, the PIC16F62X family uses a Harvard architecture with separate program and data buses, an 8-level deep 13-bit hardware stack, and 35 single-word instructions. Most instructions execute in a single 200 ns instruction cycle at 20 MHz, which gives the family strong deterministic interrupt response and predictable code execution times that are useful for real-time control loops.
Typical applications include appliance control, remote transmitters, small motor control, battery chargers, automotive accessories (non-safety subsystems), and low-end consumer products. The wide 2.0-5.5V operating range allows the same part to be used in 3.3V and 5V systems. The 'E' suffix indicates the extended industrial temperature range (-40C to +125C), making the -04E/SS variant suitable for harsh-environment industrial designs where the standard 0C to +70C part is not adequate.
When designing with this part, note that the maximum 4 MHz specification in the part number refers to the internal clock and 5V operation. At lower supply voltages the maximum oscillator frequency is derated, and engineers should consult the frequency-vs-voltage graph in the datasheet to avoid oscillator failure in brown-out conditions. The ICSP programming interface uses RB6 and RB7, so these pins must be accessible in the PCB layout.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that complement, but do not replace, the official Microchip datasheet.

主な用途
PIC16F627-04E/SS の用途: 6 件s: Appliance Control, Remote Control and RF Transmitter, Battery Chargers and Power Management, Automotive Body Electronics (non-safety), Industrial Sensor Interfaces, Consumer Electronics and Toys.
Appliance Control
The PIC16F627-04E/SS fits white-goods and small-appliance control boards where cost, deterministic response, and 5V operation are the dominant constraints. The 4 MHz internal oscillator and 200 ns instruction cycle give the CPU enough headroom for relay de-bounce, EEPROM-backed user settings, and basic user-interface tasks; the 16 I/O pins drive 7-segment displays, keypads, and triac-trigger outputs directly. The 2.0-5.5V range lets the same firmware run on 3.3V battery-backed boards and 5V mains-derived rails. Compared with a switching converter, the linear supply plus PIC16F627 combination keeps EMI low enough to pass household-appliance EMC tests without extra filtering.
おすすめ
Remote Control and RF Transmitter
Low standby current, on-chip USART, and wide supply range make the PIC16F627-04E/SS a strong fit for handheld remote controls and keyfob transmitters. The internal 4 MHz oscillator is accurate enough for 38 kHz IR carrier generation, and the CCP module generates the PWM for the IR LED directly. Sleep current drops below 1 uA with the watchdog disabled, so coin-cell designs survive multi-year standby. The extended -40C to +125C range of the -04E/SS variant handles outdoor garage-door openers and automotive keyfobs that must survive under-dash temperatures in summer. Pairing the PIC16F627 with a 433 MHz SAW-stabilized transmitter (e.g., a Micrel MICRF102) gives a complete sub-$2 RF link.
おすすめ
Battery Chargers and Power Management
The PIC16F627-04E/SS is well suited to NiCd / NiMH and small Li-ion charger controllers where on-chip comparators, programmable VREF, and PWM combine to implement CC/CV charging without external analog ICs. The two on-chip analog comparators monitor battery voltage and charge current, while the CCP module drives the switching FET through its PWM output. The wide 2.0-5.5V supply range allows the MCU to run directly from a USB or 5V adapter without an extra LDO. The internal brown-out detect holds the part in reset below the configured threshold so the charger cannot restart on a deeply discharged cell, improving safety in low-cost consumer products.
おすすめ
Automotive Body Electronics (non-safety)
Body-electronic modules such as ambient lighting controllers, mirror-adjust units, and simple body controllers often use the PIC16F627-04E/SS for its -40C to +125C operating range. The wide VDD range tolerates load-dump transients when paired with a TVS clamp and bulk capacitor on the supply pin. The on-chip USART talks to a master BCM at 10.4 kbps LIN-bus rates, and the CCP module drives LEDs and small motors through FET pre-drivers. Note that the -04E/SS is not AEC-Q100 qualified; for true AEC-Q100 systems, designers should step up to the PIC16F627A-E/SS or PIC16F1827-I/SS.
おすすめ
Industrial Sensor Interfaces
The PIC16F627-04E/SS sits naturally in industrial sensor-interface boards that read 4-20 mA loops, thermistors, or simple switch contacts and report results over a UART or LIN link. The two analog comparators with programmable VREF detect threshold crossings without an external op-amp, and the EEPROM stores calibration constants in the field. The extended -40C to +125C temperature grade suits outdoor installations and unheated enclosures. The 4 MHz internal oscillator frees the oscillator pins for general I/O on cost-sensitive boards. With 16 I/O pins and a USART, the PIC16F627-04E/SS is a single-chip solution for 8-bit industrial node designs.
おすすめ
Consumer Electronics and Toys
The PIC16F627-04E/SS is widely used in low-end consumer products, including educational toys, small LCD-driver boards, and decorative-lighting controllers, where its 1.75 KB flash, 224 bytes of RAM, and 16 I/O pins provide a balanced price-to-capability ratio. The PWM output drives RGB LEDs directly or through low-side FETs, while the comparator and VREF measure battery level for low-battery indication. The SSOP-20 package keeps the board footprint under 7 mm x 8 mm, enabling very compact end products. Designers seeking more code room for complex audio playback or Bluetooth LE pairing should consider the PIC16F1938 or PIC16F18877 as natural upgrades.

設計ノート
Decouple VDD on pin 20 with a 100 nF ceramic capacitor placed within 5 mm of the package, plus a 10 uF bulk capacitor on the same rail. The PIC16F627-04E/SS is rated 2.0V to 5.5V; when the supply is provided by a switching converter, add a ferrite bead or 10 ohm resistor in series with the VDD pin to suppress switching noise. The on-chip brown-out detect (BOD) is configured by configuration fuses and can be set to 4.0V, 2.7V, or 1.8V; enable BOD whenever the application is battery-backed to prevent code corruption on a sagging rail.
Reserve the ICSP pins RB6 (PGC) and RB7 (PGD) for in-circuit serial programming; do not place any pull-up or series resistor above 10 kohm on these lines, as it can prevent reliable programming. MCLR (pin 1) should be tied to VDD through a 10 kohm resistor, with the decoupling capacitor close to the MCLR pin rather than the resistor. For the SSOP-20 footprint, the recommended land pattern is 0.65 mm pitch with 0.40 mm pad width; refer to Microchip app note AN500 for the exact SSOP-20 PCB layout dimensions.
Estimated: oscillator start-up time is determined by configuration fuse OST and PWRT settings. At 4 MHz, expect a power-on delay of 72 ms with PWRT + OST enabled and 1.024 ms with PWRT only. Do not assume the part is in RESET without checking the TO/PD bits in the STATUS register. When migrating code from the PIC16F84 to the PIC16F627, note that the I/O mapping is different and the analog comparator pins on PORTA need ANSEL-equivalent register configuration before they can be used as digital I/O.
