PIC18F24Q10T-I/STX - 64MHz 8-bit MCU 16KB Flash 28-VQFN | Microchip

The Microchip Technology PIC18F24Q10T-I/STX is an 8-bit PIC18 XLP Q-series microcontroller running at up to 64 MHz core speed, integrating 16 KB of self-programmable Flash, 2 KB SRAM and 256 bytes of EEPROM in a compact 28-pin VQFN (4x4 mm) package. It delivers 25 general-purpose I/O, a 10-bit ADC with Computation (ADC2), a 5-bit DAC, comparators, 16-bit PWM, CCP, windowed watchdog and Core Independent Peripherals (CIPs) for noise-tolerant, deterministic real-time control. A PIC microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM/EEPROM) and configurable peripherals such as ADC, PWM, timers and communication interfaces. PIC18 is Microchip's 8-bit Harvard-architecture family tuned for low power (XLP) and rich peripheral integration; the Q10 sub-family adds intelligent analog and CIPs. Within the broader taxonomy, an MCU sits at the intersection of microprocessors and embedded controllers, enabling firmware-driven sensing, actuation and communication in products ranging from sensor nodes to appliance motor control. Key features include 1.8 V to 5.5 V single-supply operation (5 V operation enhances noise immunity), ADC2 with Capacitive Voltage Divider support for touch sensing, configurable logic cells (CLC), zero-cross detect and a peripheral pin select (PPS) that remaps digital functions to many I/O. The 64 MHz internal oscillator and 4x PLL eliminate external crystals in many designs, while the 28-VQFN 4x4 mm footprint suits compact PCBs such as wearables, IoT nodes and sensor hubs. Architecturally, the PIC18F24Q10 implements a modified Harvard core with a 16-bit instruction word, hardware multiplier and a vectored interrupt controller. ADC2 automates averaging, oversampling and threshold comparison, offloading signal conditioning from the CPU; CIPs like CLC, NCO and PWM operate autonomously, which reduces latency in real-time loops. Functional Safety (FuSa) documentation and diagnostics support safety-related designs per IEC 61508. Typical applications include capacitive touch user interfaces, IoT sensor nodes, low-power remote controls, BLDC/PMSM motor control (with companion gate drivers), HVAC/building automation and small medical/wellness devices. The wide 1.8-5.5 V supply range is convenient for direct battery or USB-powered designs. When designing, always populate the ICSPDAT/ICSPCLK pins for in-circuit serial programming and reserve a clear path to the MCLR pin for in-field firmware updates. Decouple VDD with at least 100 nF plus 1 uF ceramics close to the package, and keep ADC traces short to preserve the 10-bit noise budget.

The device targets embedded control loops that demand deterministic interrupt response, on-chip peripherals, and nanoWatt Technology power management for battery-aware applications. PIC18F microcontrollers are 8-bit Harvard-architecture MCUs built around an enhanced instruction set that retains code compatibility with the legacy PIC16 family while adding 16-bit-wide instructions, linear addressing of up to 2 MB, and single-cycle multiply for DSP-style math. The PIC18F2X1X/4X1X sub-family adds a 10-bit A/D converter, an internal oscillator block, Fail-Safe Clock Monitor, and two USART modules, positioning it as the workhorse tier between small 8-pin PIC12/16 parts and larger 40-/44-pin PIC18F4X1X devices. The Flash memory is self-programmable in-circuit, enabling bootloader and field-update workflows. Key features include 48KB Flash, 3968 bytes SRAM, 1024 bytes EEPROM, 25 digital I/O pins, a 10-channel 10-bit ADC, two comparators, two USART ports, an MSSP (SPI/I2C) module, two CCP and one Enhanced CCP capture/compare/PWM channels, and a hardware 8x8 multiplier. nanoWatt Technology provides multiple idle and sleep modes, drawing microampere-level standby current, while the Fail-Safe Clock Monitor automatically switches to the internal RC oscillator if the primary crystal fails for safety-critical loops. The architecture pairs a 16-bit instruction word with an 8-bit data path, so 1 MIPS roughly equals 1 MHz of clock for legacy code and the enhanced core adds single-cycle branches and table reads/writes that allow constant data to live in program memory for compiler-driven table-driven I/O. The interrupt controller supports prioritized vectored interrupts with shadow registers, so high-frequency ADC and timer events can preempt background loops without polling overhead, while the hardware multiplier accelerates integer math for digital filtering and motor-control compensators. Typical applications include industrial sensor conditioning, motor control and BLDC commutation, HVAC fan and damper control, USB-HID peripherals on the PIC18F2X1X/4X1X family, automotive body and chassis sub-systems, consumer appliance control boards, and general-purpose data-acquisition front-ends that pair the 10-bit ADC with the two USART links. The 28-SOIC footprint is friendly to hand-soldered prototypes and standard SMT assembly lines, and the wide 4.2-5.5 V supply lets the part run directly from a regulated 5 V rail without an LDO. When designing with the PIC18F2515, place a 100 nF decoupling capacitor within 5 mm of each power pin and tie MCLR through a 10 kohm pull-up; if in-circuit serial programming (ICSP) is required, reserve the PGC/PGD pairs and route them away from switching nodes. Plan for at least 10 KB of Flash margin if you intend to use MPLAB XC8's position-independent optimization or a USB stack on related variants.

The PIC18F2515 architecture uses a 16-bit instruction word with an 8-bit data path, single-cycle ALU operations, hardware multiply, and a 32-level hardware stack. The 10-bit ADC supports up to 11 input channels with acquisition time programmable for sensor interfacing. The device is supported by the MPLAB X IDE, MPLAB XC8 compiler, and PICkit / ICD debugger programmers, providing a complete firmware development ecosystem. The 28-SPDIP package is popular for hobbyist prototyping, breadboarding, and through-hole assembly lines where rework and socketed parts are required. Typical applications include industrial control, sensor interfacing, low-cost motor control (BLDC/PWM), USB-less human interface devices, consumer appliance controllers, and battery-powered data loggers. In motor control the CCP/PWM modules generate complementary PWM with dead-band control; in sensor systems the ADC plus EUSART streams measurements to a host; in battery applications the nanoWatt sleep currents extend operating life. When designing with this part, select a low-ESR decoupling capacitor (100 nF ceramic) close to each VDD pin and a bulk capacitor (10 uF) on the main rail. Leave MCLR either tied high through a 10 kohm resistor or driven by the programmer for in-circuit debug, and use the internal oscillator only when timing tolerance is non-critical; otherwise route a crystal on OSC1/OSC2 for accurate UART baud rates.

The Microchip Technology PIC18F252-I/SO is a high-performance 8-bit CMOS Flash microcontroller built on Microchip's PIC18 architecture, delivering 10 MIPS throughput (40 MHz max clock, 100 ns instruction cycle) in a 28-pin SOIC package with industrial -40C to +85C temperature rating. A microcontroller (MCU) is a single-chip computer integrating a CPU core, program memory (Flash/ROM), data memory (RAM/EEPROM), and programmable I/O peripherals on one die. PIC microcontrollers sit at the foundation of embedded control, spanning consumer appliances, automotive body electronics, industrial sensors, and medical devices - the 8-bit PIC18 family specifically targets applications needing higher performance and more peripherals than the baseline PIC16 family while remaining easy to program in C. Key features of the PIC18F252 include 32 KB of on-chip Flash program memory (16K x 16 words), 1536 bytes of SRAM, 256 bytes of EEPROM for non-volatile data storage, 23 digital I/O pins, a 10-bit A/D converter with up to 5 input channels, two Capture/Compare/PWM (CCP) modules, an enhanced USART, a Master Synchronous Serial Port (MSSP) configurable as SPI or I2C, and 4 timer modules.

The PIC18F252 architecture uses a Harvard memory layout with separate program and data buses, allowing instruction fetch and operand read in the same cycle. Self-programming support lets the device update its own Flash in-field, and an integrated ICD (In-Circuit Debug) interface simplifies bring-up. Operating from 4.2 V to 5.5 V, it consumes approximately 16 mA at 40 MHz in active mode and drops below 1 uA in sleep. Typical applications include industrial sensor signal conditioning, automotive body modules and instrument clusters, HVAC controllers, security alarm panels, white-goods motor control, low-end instrumentation with ADC front-ends, and USB-to-serial bridges when paired with a peripheral PHY. Designers also use the PIC18F252 in replacement of older PIC16 designs where the 16-bit instruction set, additional RAM, and enhanced peripherals unlock new features without learning a new toolchain. Design considerations include decoupling: a 100 nF ceramic should sit within 5 mm of each power pair (VDD/VSS, AVDD/AVSS), with a bulk 10 uF near the IC. The MCLR reset pin must have a 10 kohm pull-up unless tied to a supervisor; for ICSP programming, isolate the MCLR line with a resistor divider. Unused A/D channels should be tied to ground to avoid shoot-through current.

When designing with this part, plan oscillator stability for low-power modes (use the internal 31 kHz LP oscillator for sleep), keep Vdd decoupling tight to the SOIC pins, and route the ADC reference pins with a low-impedance ground return to preserve ADC accuracy.

PIC18F2520-I/SP - 8-bit 40MHz 32KB Flash MCU | Microchip | 28-SPDIP

The Microchip Technology PIC18F2520-I/SP is an 8-bit PIC18F-family Flash microcontroller running at up to 40 MHz (10 MIPS), integrating 32 KB of program Flash, 1536 bytes of SRAM, and 256 bytes of EEPROM in a 28-pin SPDIP (0.300 inch, 7.62 mm) through-hole package. It exposes 25 general-purpose I/O pins and includes a 10-bit ADC, multiple capture/compare/PWM modules, and the nanoWatt power-managed sleep modes that define the PIC18F2520 generation. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and configurable peripherals such as ADC, PWM, timers, and serial interfaces. Within the broader taxonomy, the PIC18F2520 belongs to the 8-bit MCU class, sits in the PIC18 enhanced RISC family, and is positioned by Microchip between baseline PIC10/12/16 parts and the 16-bit dsPIC/PIC24 line. The 28-pin SPDIP variant is the classic DIP-28 form factor used for prototyping, breadboarding, and legacy industrial controller cards where socketed replacement is desirable. Key features include a C-optimized enhanced Harvard architecture with 8x8 single-cycle hardware multiply, an internal oscillator block covering 31 kHz to 8 MHz, a Fail-Safe Clock Monitor, two 8-bit and three 16-bit timers, an Enhanced Capture/Compare/PWM (ECCP) module, two MSSP blocks supporting SPI and I2C (master/slave), an Enhanced USART, 10-bit ADC with up to 10 channels, two analog comparators, and a programmable Low-Voltage Detect module. The on-board nanoWatt technology offers Idle, Sleep, and low-power Timer1 oscillator operation. Typical applications include industrial control panels, motor drive signal conditioning, sensor interface boards, low-power remote sensor nodes, legacy PIC18 firmware upgrades that need more Flash and peripherals than older PIC16 designs, and educational kits where the SPDIP-28 footprint simplifies breadboard use and socketed replacement. Designers should provide a stable 4.2 V to 5.5 V supply, place a 100 nF decoupling capacitor close to VDD, route MCLR with a 10 kohm pull-up, and budget for the in-circuit serial programming (ICSP) header required by PICkit programmers. Industrial-temperature (-40C to +85C) operation is supported. This page consolidates verified distributor pricing, drop-in pin-compatible alternatives in the SPDIP-28 footprint, and application guidance drawn from the Microchip PIC18F2420/2520/4420/4520 datasheet that the bare DigiKey or Mouser listing does not provide.

PIC18F2520T-I/ML - 8-bit MCU, 32KB Flash, 40MHz, 28-QFN | Microchip
PIC18F2520T-I/ML

PIC18F2520T-I/ML - 8-bit MCU, 32KB Flash, 40MHz, 28-QFN | Microchip

The Microchip Technology PIC18F2520T-I/ML is an 8-bit PIC18F-family flash microcontroller running up to 40 MHz (10 MIPS with 4x PLL active) and integrating 32 KB of Flash program memory plus 1.5 KB of data EEPROM, packaged in a 28-pin QFN (ML, 6x6 mm) with 25 digital I/O pins. The device operates across an industrial temperature range of -40 °C to +85 °C with a supply voltage of 4.2 V to 5.5 V (a 2.0 V–5.5 V "LF" variant also exists, but the "I/ML" suffix denotes the standard 4.2 V minimum version). What is a PIC18 microcontroller? The PIC18 is Microchip's high-end 8-bit RISC architecture family, positioned above PIC16 and below the 16-bit dsPIC33/PIC24 line. PIC18 parts combine a Harvard bus, a 16-bit instruction word with 8-bit data path, hardware multiply, a C-optimized instruction set and self-programmable Flash, making them suited to mid-range embedded control where deterministic timing, peripheral richness and stable firmware updates are required. Key features of the PIC18F2520 include 1.5 KB SRAM (plus 1.5 KB general-purpose EEPROM), a 10-bit ADC with up to 10 input channels, one Enhanced USART, one MSSP (SPI/I2C), two CCP and one Enhanced CCP module, two 8-bit and three 16-bit timers, nanoWatt power management, an ICD/ICSP debug interface, and 25 mA source/sink capability on each I/O with internal weak pull-ups. The wide operating range and peripheral set target appliance control, sensing, motor pre-driver, lighting, USB-serial bridge co-processors and field-replaceable industrial nodes. According to the manufacturer datasheet, the device is qualified to AEC-Q100 for automotive PIC18F2520-I/ML variants. Architecture-wise, the PIC18F2520 uses a 16-bit wide instruction pipeline with 31-level hardware stack, hardware multiply (8x8 in one cycle), 10-bit pipelined ADC with internal 4-channel mux and self-calibration, and a low-power "nanoWatt" feature set including run, idle, sleep and a 32 kHz secondary oscillator with Timer1 real-time clock operation. Multiple oscillator modes (HS, XT, LP, RC, EC, INTIO) plus 4x PLL on the standard 40 MHz silicon allow flexible clocking from internal 31 kHz through external 40 MHz sources. Typical applications span USB HID class devices, industrial control panels, sensor signal conditioning, automotive body and HVAC ECUs (Q-graded), white goods motor control, smart metering, lighting ballasts, and embedded data logging. The 28-QFN variant (PIC18F2520T-I/ML, T = Tape & Reel) is favored where board height is constrained. A critical design consideration: the PIC18F2520 I/O banks are not 5 V-tolerant when the part is supplied below 4.2 V, so do not drop to 3.3 V operation on this "I/ML" version; either use a 5 V rail or move to the PIC18LF2520. Decoupling requires one 100 nF X7R cap per supply pin and a 10 µF bulk capacitor, with the Vcap pin on PIC18F core regulated devices carrying 8 µF–12 µF for the internal 2.5 V regulator. Trace lengths to MCLR must be short to prevent in-circuit debug noise. This page synthesizes real distributor pricing, a same-family drop-in matrix, and design considerations that go beyond the manufacturer datasheet — including migration paths between PIC18F2520 and PIC18LF2520 and QFN-28 package decisions versus the SPDIP/SOIC siblings.

The 28-pin SOIC form factor is one of the most common surface-mount footprints for industrial controllers. Key features include 25 digital I/O pins, an internal 31 kHz to 8 MHz oscillator, fail-safe clock monitor with safe shutdown on clock failure, a separate-oscillator watchdog timer with on-chip RC, and hardware peripherals including 10-bit ADC, comparators, PWM, and USART. According to the Microchip datasheet (DS39667), the device operates from 4.2V to 5.5V and supports in-circuit serial programming (ICSP) and in-circuit debugging (ICD). Typical applications include industrial control panels, automotive body and convenience electronics, sensor signal conditioning nodes, motor control sub-systems, USB-to-UART bridging via companion transceivers, and home appliance user-interface boards. The internal oscillator and wide temperature range make it suited for unattended installations. When designing with this device, ensure decoupling on every VDD/AVDD pin (100 nF minimum plus a bulk 10 uF), follow Microchip's recommended ICSP ICP layout for in-circuit programming access, and budget the ADC sampling time against the internal TAD clock to keep conversion errors below 1 LSB.

The Microchip Technology PIC18F2523-E/SO is a high-performance 8-bit RISC flash microcontroller featuring 32KB of program memory, 1.5KB of RAM, and a 12-bit ADC with up to 10 channels, packaged in a 28-pin SOIC (SO) wide-body IC. The device operates from a 4.2V to 5.5V supply and supports clock speeds up to 40MHz (10 MIPS), making it well suited for embedded control applications requiring deterministic real-time response and on-chip analog integration. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), working memory (RAM), and a rich set of peripherals on a single silicon die. Within the broader semiconductor taxonomy, an MCU belongs to the family of embedded processors, sitting between simple digital logic ICs and full application processors. PIC18F devices specifically employ an enhanced Harvard RISC architecture with a C-compiler-friendly instruction set, hardware 8x8 single-cycle multiplication, and a priority-level interrupt controller that simplify firmware development for real-time embedded products. The PIC18F2523 distinguishes itself with a 12-bit ADC (vs. 10-bit on older PIC18F parts), an internal oscillator block tunable from 31 kHz to 8 MHz and up to 32 MHz via 4x PLL, a Fail-Safe Clock Monitor that permits safe shutdown on clock loss, an Enhanced Capture/Compare/PWM (ECCP) module, and three 16-bit timers. The wide-body 28-SOIC footprint offers generous board-level handling for industrial temperature grades (-40C to +125C) and through-hole-style manufacturing flows. Typical applications include industrial sensor signal conditioning, motor control loops (BLDC, stepper, brushed DC via PWM), home-automation user interfaces, automotive body and HVAC modules, USB-to-UART bridging front ends, and general-purpose embedded control. The on-chip 12-bit ADC removes the need for an external converter when interfacing with analog sensors, reducing BOM cost and PCB area. Designers should review the PIC18F2523 datasheet for the pin-compatibility migration path to the PIC18F25K22 family when modernized peripherals, lower power, and CIP (Core Independent Peripherals) are desired. The E suffix denotes the -40C to +125C extended temperature grade, and the /SO suffix denotes the 28-pin wide-body SOIC package.
