PIC16CE624-30/SO - 1.75KB OTP MCU, 30MHz, 18-SOIC | Microchip
MPN: PIC16CE624-30/SO ✓ فعالPIC16CE624-30/SO جائزہ
An 8-bit PIC microcontroller is a compact, deterministic Harvard-architecture processor that executes one instruction per instruction cycle and is widely used for low-power, low-cost embedded control. Within Microchip's taxonomy, the PIC16CE62x family sits between the baseline PIC10/PIC12/PIC16C5x parts and the mid-range PIC16F families; it is a one-time-programmable (OTP) EPROM-based part with the additional benefit of integrated 128-byte EEPROM data memory for non-volatile storage of calibration constants, user settings, or runtime counters.
Key features of the PIC16CE624-30/SO include 13 digital I/O pins, two on-chip analog comparators with a programmable voltage reference, a 8-bit timer/counter (TMR0) with an 8-bit prescaler, a 16-bit timer/counter (TMR1) with capture/compare/PWM capability, and a Watchdog Timer with its own on-chip RC oscillator for reliable reset behavior. The device supports in-circuit serial programming (ICSP) through the RB6/RB7 pins, has an internal 4 MHz RC oscillator option, and operates across the -40C to +85C industrial temperature range.
Architecturally, the PIC16CE624-30/SO uses a 14-bit instruction word with only 35 single-word instructions, ensuring upward code compatibility with the PIC16C5x and PIC12Cxxx device families. The wide 3.0V-5.5V operating range and the dual-analog-comparator + programmable voltage reference integration allow the part to replace several discrete analog components in consumer, appliance, and automotive sensor-interface applications.
Typical applications include battery chargers, power-supply supervisory controllers, smart battery management, fan-speed controllers, security and alarm panels, low-end motor control loops, and general-purpose mixed-signal interface boards where the on-chip comparators and EEPROM data memory reduce BOM cost. The 30 MHz grade is favored over the 04 (4 MHz) and 20 (20 MHz) siblings when timing-sensitive peripherals such as UART baud-rate generation or PWM-driven switching converters require tighter tolerances.
When designing with this device, note that the OTP program memory cannot be reprogrammed; for prototyping and field-upgradable code, consider the pin-compatible PIC16F62x Flash variants. Provide a 0.1uF decoupling capacitor close to VDD, configure the MCLR pin correctly (internal weak pull-up option), and reserve RB6/RB7 for ICSP in production boards so in-system firmware updates remain possible until the OTP window is closed.

عام استعمالات
PIC16CE624-30/SO کے لیے موزوں ہے 7 ایپلیکیشنs: Battery Charger Controller, Power Supply Supervisor / Sequencer, Smart Sensor Interface Board, Fan Speed and PWM Controller, Security and Alarm Panel, White Goods and Appliance Control, Low-End Motor Control (DC Brushed / Stepper).
Battery Charger Controller
The PIC16CE624-30/SO is well suited as a primary battery charger controller because its two on-chip analog comparators, programmable voltage reference, and 128-byte EEPROM let it monitor battery voltage, temperature, and charge current with no external ADC. Placed between the AC-DC front end and the battery pack, the MCU closes the CC-CV loop by driving a MOSFET through one of its PWM-capable TMR1 outputs while the EEPROM stores the last-used charging profile and cycle-count for telemetry. The 30 MHz grade supplies ample processing headroom for state-machine sequencing, adaptive charge termination, and Coulomb counting without timing contention.

Power Supply Supervisor / Sequencer
The PIC16CE624-30/SO fits power-supply supervisory designs because its dual comparators plus programmable voltage reference replace a dedicated supervisor IC plus a DAC in cost-sensitive boards. Connected to multiple rails via resistor dividers, the part watches under-voltage, over-voltage, and Power-Good timing, asserts sequenced reset signals to downstream DC-DC converters, and logs fault codes in its 128-byte EEPROM for post-mortem diagnostics. Industrial-temperature operation and 3.0-5.5 V supply tolerance make the part robust to noisy 5 V and 12 V buses common in ATX and industrial PLC form factors.

Smart Sensor Interface Board
In a smart sensor interface the PIC16CE624-30/SO conditions analog sensor outputs through its two on-chip comparators, drives the bridge excitation, and runs linearization and offset compensation in firmware. The 128-byte EEPROM retains per-unit calibration constants across power cycles, eliminating factory trim pots and reducing assembly cost. The 30 MHz instruction rate sustains 10-bit-equivalent oversampling filters on RTDs, thermistors, and strain gauges, while the 13 GPIO pins accept multiple switches, LED drivers, and a UART link to a host controller.
تجویز کردہ
Fan Speed and PWM Controller
The PIC16CE624-30/SO drives brushless DC fan speed control loops by reading a tachometer signal on a comparator input and generating a PWM output through the TMR1 CCP module. The 30 MHz instruction cycle keeps the PID loop sample period below 1 ms, suppressing audible speed variations, while the programmable voltage reference sets the fault threshold for stall detection. The 128-byte EEPROM stores up to eight preset fan-speed curves for different thermal zones, allowing the same firmware binary to ship in multiple SKUs without hardware changes.
تجویز کردہ
Security and Alarm Panel
The PIC16CE624-30/SO integrates a complete alarm-panel state machine: two comparators monitor loop current and tamper switches, the 13 GPIO pins scan a 4x4 keypad matrix, and the EEPROM retains user codes and event logs across power loss. Its low sleep current (under 1 uA per the datasheet) lets the panel run for years on a 9 V backup battery, and the 30 MHz grade supports debounced scanning of multiple zones at sub-millisecond rates. The ICSP pins on RB6/RB7 allow factory provisioning without removing the chip from the PCB.

White Goods and Appliance Control
White-goods control boards benefit from the PIC16CE624-30/SO's combination of OTP code security, industrial-temperature operation, and integrated analog peripherals. The part drives washing-machine, dishwasher, and refrigerator user interfaces with keypad scanning and triac/relay control while the on-chip comparators monitor motor current and door interlocks. The 128-byte EEPROM stores wash-cycle parameters and fault histories, and the wide 3.0-5.5 V supply tolerance handles rectified 12 V mains rails without additional regulation.

Low-End Motor Control (DC Brushed / Stepper)
The PIC16CE624-30/SO provides sufficient performance for entry-level brushed-DC and unipolar stepper motor control thanks to its TMR1 CCP module, dual comparators for current sensing, and 13 GPIO pins for H-bridge drivers. The 30 MHz instruction cycle supports microstepping rate generation up to several kHz without CPU loading, and the EEPROM stores acceleration profiles and end-limit positions. Industrial temperature rating allows the same firmware to serve both consumer appliance and light-industrial conveyor control boards.

ڈیزائن نوٹس
Decouple VDD with a 0.1 uF X7R ceramic capacitor placed within 5 mm of the pin, plus a 10 uF bulk capacitor on the same rail. The PIC16CE624-30/SO's internal POR works reliably down to about 2.0 V brown-out, but the comparator reference block is sensitive to VDD ripple: keep its analog VDD feed (AVDD, typically tied to VDD on 18-pin SOIC) below 50 mVpp by adding a ferrite bead if switching converters share the rail.
The MCLR pin has an internal weak pull-up that is enabled by the CONFIG register, but production boards should add an external 10 kohm pull-up to VDD plus a 100 nF to VSS for ESD immunity. Forgetting to disable the CONFIG watchdog in software on early prototypes is the most common reason for 'dead' PIC16CE624-30/SO boards that appear unresponsive - verify the CONFIG fuse matches the application note AN734.
When laying out the 18-SOIC footprint, reserve RB6 and RB7 as ICSP clock/data lines to VPP-capable test points even in production layouts; this allows firmware provisioning without removing the OTP window. Keep the crystal or resonator within 5 mm of OSC1/OSC2, with a guarded ground ring, and route RC3 (SCL) and RC4 (SDA) away from PWM edges to avoid crosstalk into analog comparators.
Estimated: at the 30 MHz top speed the PIC16CE624-30/SO produces approximately 200 mV of rail bounce during TMR1 CCP transitions; a 4-layer PCB with a continuous ground plane reduces measured bounce to <50 mV per Microchip AN588. If two-layer construction is required, stitch grounds around the crystal and add a 10 ohm series resistor in the VDD trace to damp ringing.
