The device integrates 8 KB of Flash program memory (4K x 16 words), 512 bytes of SRAM, and 256 bytes of EEPROM, providing a balanced on-chip memory architecture for embedded control applications. What is a PIC18F microcontroller? The PIC18F family is Microchip's high-performance 8-bit microcontroller line based on an enhanced RISC architecture with 16-bit instructions and an 8-bit data path. PIC18F parts use Harvard architecture, support C-compiler-friendly development, and provide peripherals such as A/D converters, PWM, comparators, and configurable serial ports (SPI/I2C). Within the broader taxonomy, PIC18F MCUs sit between baseline PIC10/12/16 and 16-bit PIC24/dsPIC families, making them well suited for mid-complexity real-time control. Key features of the PIC18F2321-I/SP include a 10-bit A/D converter with up to 10 channels, two analog comparators, two capture/compare/PWM (CCP) modules, a synchronous serial port configurable as SPI or I²C, and nanoWatt Technology power management for low-power applications. The device operates from 4.2 V to 5.5 V and supports an industrial temperature range of -40 °C to +85 °C as denoted by the "I" suffix. With 25 I/O pins and an enhanced instruction set of 77 single-word instructions, the part targets applications requiring deterministic real-time response. Architecturally, the PIC18F2321 uses an 8-bit data path with a 16-bit instruction set, allowing 10 MIPS throughput at 40 MHz CPU clock. Internal oscillator options, a programmable brown-out reset, and a low-power sleep mode further support battery-powered designs. The combination of on-chip EEPROM, flexible peripherals, and the established MPLAB development ecosystem enables rapid prototyping and production scaling. Typical applications include industrial control systems, sensor interface modules, low-power remote sensing nodes, consumer appliance controls, and small motor/lighting controllers. The 28-SPDIP package is preferred for prototyping, breadboarding, and legacy designs where through-hole assembly is required or where mechanical robustness matters. When designing with the PIC18F2321-I/SP, ensure that your supply decoupling (0.1 µF + 10 µF) is placed close to VDD/AVDD/VSS/AVSS, and configure the configuration bits (oscillator, watchdog, brown-out, code protection) appropriately using MPLAB X IDE.

It integrates 8 KB of flash program memory (4K x 16 words), 512 bytes of SRAM, and 256 bytes of EEPROM data memory on-chip. The device is built around Microchip's enhanced RISC architecture with 77 single-word instructions and a C-compiler-friendly instruction set. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, data EEPROM, and configurable peripherals. PIC18F-series microcontrollers belong to Microchip's enhanced 8-bit PIC family, sitting in the hierarchy: PIC18 MCU -> 8-bit microcontroller -> embedded controller -> semiconductor IC. This positioning places the PIC18F2321 well above baseline 8-bit parts (PIC16) for compute density while remaining far below 32-bit Cortex-M devices in price-sensitive applications. Its nanoWatt Technology power management makes it suitable for both line-powered and battery-operated designs.

The device operates from 4.2 V to 5.5 V and supports industrial -40 °C to +85 °C temperature range. In-circuit debugging via ICD and self-programmability are supported, simplifying field updates. The flash memory is rated for 100K erase/write cycles minimum and data EEPROM for 1M cycles. The PIC18F2321 architecture combines an 8-bit ALU with a 16-bit instruction word, providing higher code density than 12-bit PIC16 cores while retaining single-cycle execution on most instructions. Its deep 16-level hardware stack, hardware multiplier (8 x 8 in one cycle), and prioritized interrupt controller allow real-time response for control loops, while the nanoWatt idle/sleep modes drop current consumption to microamp levels for battery-friendly idle behaviour. Typical applications include industrial control systems, sensor signal conditioning with on-chip A/D conversion, motor control with PWM drivers, low-cost consumer appliances, HVAC controllers, and battery-powered instruments. The integrated 10-bit A/D and comparators reduce external analog components in closed-loop designs, and the SSOP-28 footprint enables compact PCB layouts under 50 mm^2. When designing with this part, ensure the MCLR reset circuit includes the required 10 kΩ pull-up to VDD and a 100 nF capacitor to ground for proper power-on reset behaviour. Unused I/O pins should be configured as outputs and tied low to minimise current draw, and the configuration bits must be set correctly for oscillator mode and watchdog timer behaviour before code execution begins.

The Microchip Technology PIC18F2321T-I/ML is a 10 MIPS CMOS Flash-based 8-bit microcontroller from the PIC18F family, packaged in a 28-pin QFN (ML, 6x6 mm) with exposed thermal pad. It integrates 8 KB (4K x 16) of Flash program memory and 512 bytes of RAM, executes instructions in 100 ns at 40 MHz, and offers 25 digital I/O pins, a 10-channel 10-bit Analog-to-Digital Converter, plus I2C, SPI, and USART connectivity. The 'T' suffix denotes Tape and Reel packaging, while 'I' denotes the industrial -40C to +85C operating temperature range. A microcontroller (MCU) is a single-chip computer that combines a CPU, non-volatile program memory (Flash/ROM), volatile working memory (RAM), and programmable peripherals on one die. PIC microcontrollers from Microchip use a Harvard RISC architecture with a small, fixed instruction set (77 single-word instructions on this device) that simplifies software development, shortens interrupt latency, and yields deterministic execution. Within the broader taxonomy, the PIC18F2321 sits in the hierarchy: MCU -> 8-bit MCU -> PIC18 enhanced family -> nanoWatt power-managed variants. nanoWatt technology adds multiple low-power sleep modes that drop supply current to the microamp range, enabling battery-powered designs. Key differentiating features of this device include 8 KB of self-programmable Flash (in-circuit serial programming via ICSP), 256 bytes of EEPROM data memory, an internal oscillator block, brown-out reset (BOR), a 10-bit ADC with 10 channels, dual analog comparators, a Capture/Compare/PWM (CCP) module, and nanoWatt sleep modes that typically idle below 1 uA. The PIC18 instruction set is backwards-compatible with PIC16 code while adding prioritized interrupts, hardware multiply, and an 8-bit-wide data path with 16-bit instruction words. Architecturally, the PIC18F2321 uses a 14-bit instruction word fetched from Flash and executed by an 8-bit ALU in one instruction cycle (4 Fosc). The internal oscillator trims to +/-1% across voltage and temperature, removing the need for an external crystal in cost-sensitive applications. Peripherals map onto the same peripheral bus used across the PIC18F family, allowing easy code migration to the 40-pin (PIC18F4321) or 44-pin (PIC18F4520-class) siblings with little or no code change. Typical applications include industrial sensor interfaces, low-cost motor control loops, small appliance controllers, USB-to-UART bridges when paired with a USB transceiver, consumer white goods, and battery-powered data loggers. The combination of nanoWatt modes and 10-bit ADC accuracy makes it well suited to portable instrumentation and remote sensor nodes. When designing with this part, choose your oscillator source early - the internal RC oscillator saves BOM cost but is less accurate than an external crystal for timing-critical UART or USB communications. Always populate the ICSP connector footprint even in production designs, as it enables in-field firmware updates and simplifies prototype bring-up.

Architecturally, the device uses a Harvard architecture with separate program and data buses, 16-bit instructions, an 8-bit data path, and an 8x8 hardware multiply engine. nanoWatt XLP technology provides multiple idle and sleep modes plus ultra-low-power watchdog and RTCC operation, making the part attractive for battery-powered sensor nodes. The PLL allows the internal 16 MHz oscillator to drive the CPU up to 64 MHz, enabling tighter timing resolution while keeping external crystal requirements minimal. Typical applications include low-power IoT sensor nodes, portable battery-powered instruments, consumer white-goods control panels, automotive body electronics (non-AEC-Q100 due to E-grade only), lighting control, and small home appliances. The wide operating voltage and robust peripherals also suit industrial data loggers and remote control transmitters. Engineers choose this part when 8 KB of Flash and 25 I/O lines are sufficient, the SSOP-28 footprint is acceptable, and ultra-low sleep current is critical for energy harvesting or battery-life targets. Design consideration: an external decoupling capacitor of 100 nF (plus 10 uF bulk) should be placed within 5 mm of VDD, and the MCLR pin requires a 10-50 kohm pull-up to VDD if unused internal pull-ups are not enabled. The ICSP/ICD pins (RB6/RB7) must not be loaded heavily in target applications to preserve in-circuit debug operation.

Within the broader taxonomy, an 8-bit MCU like this one is positioned between 4-bit legacy controllers and 32-bit Cortex-M0/M4 devices, fitting applications that need deterministic low-power control without the cost or complexity of an ARM core. It belongs to the power management and embedded control hierarchy used in industrial, consumer, and automotive subsystems. Key features include a 10-bit ADC with up to 14 input channels, two 8-bit and three 16-bit timers, two Enhanced USART modules, MSSP (SPI/I2C), and nanoWatt Technology power management for ultra-low sleep currents. The wide 1.8V to 3.6V operating range with internal voltage regulator allows single-supply designs. The internal 16 MHz RC oscillator plus 4x PLL eliminates external crystals in many designs, freeing two pins for additional GPIO. Typical applications include industrial sensor nodes, low-power battery telemetry devices, LED lighting controllers, motor control peripherals, USB-to-UART bridges (with companion parts), and consumer appliance control panels. The 256-byte EEPROM is particularly useful for storing calibration data, configuration, and user preferences without external memory. When designing with this part, place a 100 nF decoupling capacitor directly across VDD/VSS pairs near the IC pins, and follow Microchip's recommended ICSP programming header layout for in-circuit firmware updates. Engineers migrating from PIC18F2XK20 series predecessors benefit from code compatibility and identical peripheral register maps.

The PIC18 architecture extends the baseline PIC16 instruction set with a 16-bit wide program word, hardware multiply, and linear addressing of up to 2 MB, placing it in the mid-range PIC family (PIC18) within the broader microcontroller hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. nanoWatt XLP technology adds sleep currents as low as the nanoampere range, suitable for battery-powered and energy-harvesting designs. Key features of the PIC18F23K22 family include 8KB self-programmable Flash with program counter relative addressing, two Enhanced USART modules supporting RS-485/RS-232 and LIN, two MSSP modules for SPI and I2C (master/slave), a 10-bit ADC with up to 17 channels and auto-acquisition, three ECCP modules, two CCP modules, and a 16-bit Enhanced Timer. The -I/MV industrial-grade variant operates over -40C to +85C and is qualified to MSL1. Typical applications include low-power remote sensors, smart metering, consumer appliances, LED lighting controllers, automotive body and climate subsystems, and industrial control nodes. The wide 2.3V to 5.5V input range and 16 MIPS throughput suit battery-powered edge nodes that must wake, sample, transmit, and sleep efficiently. When designing with the PIC18F23K22-I/MV, place decoupling capacitors (100 nF + 10 uF) within 3 mm of each VDD/VSS pair, tie the exposed pad to a low-impedance ground plane, and use the on-board ICD pins for in-circuit debugging. A newer Microchip recommendation is the PIC18F24Q10 family for new designs with equivalent peripherals plus Core Independent Peripherals (CIPs).

PIC18F23K22-I/SO

PIC18F23K22-I/SO - 8-bit XLP MCU, 64MHz, 8KB Flash | Microchip

The Microchip PIC18F23K22-I/SO is an 8-bit PIC18 XLP microcontroller delivering 64 MHz CPU performance, 8 KB of Flash program memory, 512 bytes of SRAM, and 256 bytes of EEPROM in a 28-pin SOIC package. It supports an industrial operating temperature range of -40C to +85C and runs from a 2.3 V to 5.5 V supply, making it compatible with both 3.3 V and 5 V system rails. An 8-bit microcontroller (MCU) is a programmable system-on-a-chip that combines a CPU, non-volatile program memory (Flash/ROM), working RAM, and a rich set of peripherals (GPIO, timers, ADC, communication interfaces) on a single silicon die. The PIC18 architecture sits in the middle of Microchip's 8-bit MCU portfolio: more capable than the baseline PIC10/PIC12/PIC16 families, with a richer instruction set, larger address space, and C-friendly hardware stack, while remaining cheaper and lower-power than 16-bit PIC24 or 32-bit parts. XLP (eXtreme Low Power) is Microchip's brand for nanoWatt-class sleep current, targeting battery-powered and energy-harvesting designs. Key features of the PIC18F23K22 include nanoWatt XLP technology with sub-uA sleep currents, an integrated 10-bit ADC with up to 17 channels, multiple Enhanced USART, MSSP (SPI/I2C), and PWM modules with up to 7 independent outputs. The 28-pin SOIC package exposes 25 I/O pins and supports in-circuit serial programming (ICSP) and ICD debug through two pins, eliminating the need for an external programmer header in many designs. Architecturally, the PIC18F23K22 uses a Harvard RISC core with 49 instructions and hardware multiply, executes most instructions in one cycle, and integrates a wide peripheral mix aimed at sensor reading, motor/signal timing, and serial communication. It is widely used as the lowest-cost 8-bit option for engineers migrating away from PIC16 designs that need more memory or peripherals. Typical applications include low-power IoT sensor nodes, battery-powered HVAC and home automation, automotive body and accessory subsystems, white-goods and small appliance control, industrial sensor interfaces, and consumer remote controls. Per Microchip's product page, the part is in production and the recommended migration target is the newer PIC18F24Q10 family. When designing with this device, place 100 nF decoupling close to each VDD pin and use a 10 uF bulk capacitor near the regulator. Leave RA5/MCLR/VPP accessible for ICSP, and verify the ADC reference is properly bypassed when using external Vref+. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes not aggregated in the manufacturer datasheet, helping procurement and design engineers evaluate the PIC18F23K22-I/SO against its siblings and newer PIC18 replacements.

PIC18F23K22-I/SP

PIC18F23K22-I/SP - 8-bit 64MHz 8KB Flash MCU | Microchip

The Microchip Technology PIC18F23K22-I/SP is an 8-bit PIC18 microcontroller built on the nanoWatt XLP extreme-low-power platform, delivering up to 16 MIPS performance from a 64 MHz internal oscillator while housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. The device integrates 8 KB of self-programmable Flash program memory (4K x 16 words), 768 bytes of RAM, and 256 bytes of EEPROM, and operates across a wide 1.8 V to 5.5 V supply range suitable for both battery-powered and 5 V industrial rails. The -I/SP suffix designates the industrial temperature grade (-40 °C to +85 °C) and SPDIP package. A PIC18 microcontroller is a member of the 8-bit RISC (Reduced Instruction Set Computer) family originally developed by General Instrument's Microelectronics Division and now maintained by Microchip Technology. PIC18 cores extend the earlier PIC16 architecture with a 16-bit instruction word, hardware multiply, a linear program/data memory map, and a C-friendly compiler target, sitting within the broader hierarchy: microcontroller -> embedded controller -> semiconductor IC. The PIC18F23K22 specifically belongs to the enhanced mid-range "K22" sub-family which adds nanoWatt XLP sleep modes, a 12-bit ADC option on larger pin counts, and on-chip 5-bit DAC peripherals. Key features include seventeen 10-bit ADC channels, a 5-bit DAC with rail-to-rail output, seven timer/counter modules, three PWM channels with auto-shutdown, two I2C, two SPI, and two EUSART (with LIN) interfaces, plus a 32 kHz RTCC for low-power timekeeping. The mTouch capacitive-touch peripheral, configurable on-chip pull-ups, and a hardware CRC engine enable sensor and robust-communication applications without external components. A configurable low-power BOR and extended WDT round out the safety feature set. Typical applications include battery-powered sensor nodes, capacitive-touch user interfaces, low-power remote controls, LIN-based automotive body controllers (non-safety), industrial control panels, and hobbyist/maker projects that benefit from breadboard-friendly through-hole packaging. The wide operating voltage and XLP modes allow direct Li-Ion or 2xAA cell operation with run currents measured in microamperes. Designers should note that the 28-pin SPDIP footprint exposes 24 GPIO (some multiplexed with analog peripherals), and decoupling requires at least 0.1 µF plus a bulk capacitor near the VDD/VSS pair. For sleep-mode sub-µA operation, the ADC must be disabled, unused peripherals clock-gated, and pins driven to defined logic levels. When migrating to a smaller package, choose the -I/SS (28-SOIC) or -I/MV (28-UQFN) variants which share the same pinout. This page consolidates distributor pricing, same-family drop-in alternatives, and practical design considerations beyond the manufacturer datasheet.
