PIC18F4458-I/ML - 8-bit 48MHz USB MCU 24KB Flash 44-QFN | Microchip

The Microchip PIC18F4458-I/ML is an 8-bit PIC18 microcontroller running up to 48 MHz with 24 KB Flash, 2 KB SRAM, and 256 Bytes EEPROM, integrated Full-Speed USB 2.0, a 12-bit ADC, and nanoWatt power management, housed in a 44-pin QFN (8x8 mm) package. What is an 8-bit MCU with integrated USB? An 8-bit microcontroller is a single-chip computer built around an 8-bit data path, optimized for deterministic control, low power, and small code footprint. PIC18F devices extend the baseline PIC16 architecture with a 16-bit instruction word, C-friendly addressing, and richer peripherals. Within the broader taxonomy, PIC18 belongs to the microcontroller -> embedded controller -> semiconductor family, and the 44-QFN "/ML" suffix positions it as the surface-mount variant of the PIC18F4458 family (others include /PT TQFP and /P PDIP). Key features include 24 KB (12K x 16) of enhanced Flash with self-programming support, 2 KB SRAM, 256 Bytes EEPROM, 35 digital I/O pins, an internal 31 kHz to 8 MHz oscillator with PLL for 48 MHz operation, a 12-bit A/D converter with up to 13 input channels, two analog comparators, two CCP modules plus an enhanced CCP, three serial ports (FS-USB 12 Mbit/s, I2C, SPI up to 10 Mbit/s), and a USART with LIN support. The nanoWatt feature set provides idle, sleep, and low-power Timer1 oscillator modes that let the device draw microamps in standby. Architecturally, the PIC18F4458 uses an enhanced Harvard bus with a 16-bit flash program word and an 8-bit data path, enabling C-friendly operation while keeping interrupts and peripheral triggers fully deterministic. The integrated USB SIE handles Full-Speed (12 Mbit/s) USB 2.0 without an external transceiver or external oscillator when paired with the internal 48 MHz PLL, dramatically reducing BOM cost for USB peripherals. The 12-bit ADC is paired with a 5-channel input mux for mixed analog/digital sensor nodes. Typical applications include Full-Speed USB human-interface devices (HID keyboards, mice, custom joysticks), USB-to-UART bridges, low-cost data loggers with analog sensors, industrial control panels, and consumer accessories needing a wired connection to PCs or chargers. The 24 KB Flash comfortably fits USB stack and CDC/HID class drivers alongside application logic. When designing with this device, follow the recommended USB bus-power decoupling (100 nF high-frequency + 4.7 uF bulk) and place the VBUS sense resistor within 10 mm of the D+ line. Note that part number suffix /ML denotes the 44-pin QFN package; the /PT variant is TQFP-44 and /P is PDIP-40 - all three share the same silicon so firmware is portable, but PCB footprints and pinouts differ. This page synthesizes distributor pricing, same-brand drop-in alternatives (PIC18F4455, PIC18F4450), cross-brand parametric equivalents, and practical design notes not found in the manufacturer datasheet alone.

PIC18F448-I/P - 8-bit 40MHz 16KB Flash MCU w/ CAN | Microchip

The Microchip Technology PIC18F448-I/P is a high-performance 8-bit PIC18-family CMOS Flash microcontroller with integrated CAN (Controller Area Network) peripheral, packaged in a 40-pin PDIP (DIP-40). It delivers up to 10 MIPS (40 MHz clock) and provides 16 KB of Flash program memory, 768 bytes of RAM, and 256 bytes of EEPROM. The part operates from 2.0 V to 5.5 V and offers 34 digital I/O pins plus a 10-bit A/D converter, making it well suited to automotive, industrial, and embedded-control designs that require on-chip CAN. What is a PIC18F microcontroller? The PIC18F is Microchip's enhanced 8-bit family built on a modified Harvard RISC architecture. PIC18F devices belong to the broader 8-bit microcontroller category, which sits under the embedded MCU hierarchy (microcontroller -> microcontroller IC -> semiconductor). The PIC18F instruction set uses 77 single-word instructions, so most instructions execute in one instruction cycle (4 clock periods), which is why a 40 MHz oscillator yields 10 MIPS throughput. Compared with base-line PIC16F parts, the PIC18F family adds higher program/data memory, larger register sets, and richer peripherals such as CAN, USB, and enhanced capture/compare modules. Key differentiating features of the PIC18F448 include on-chip ECAN-ready CAN module, 10-bit ADC with up to 8 channels, two capture/compare/PWM (CCP) modules plus an enhanced ECCP, two USART ports, MSSP (SPI/I2C), 10 MIPs throughput, and self-programmable Flash. The /I suffix in the part number indicates the industrial temperature range of -40 C to +85 C, and the /P indicates the PDIP-40 package. The PIC18F448 architecture combines a 16-bit-wide instruction word with an 8-bit data path, allowing single-cycle access to Flash while preserving byte-level peripheral operation. The integrated CAN engine supports CAN 2.0B active frames at up to 1 Mbps bit rate, providing hardware message acceptance filtering and interrupt-driven transmission. The Flash memory is qualified for at least 100,000 erase/write cycles and supports ICSP (In-Circuit Serial Programming) for production-line or field updates. Typical applications for the PIC18F448 include CAN nodes in automotive body and chassis electronics, industrial sensor nodes, building-automation nodes, low-end PLCs, and CAN bridges. The 34 I/O pins plus analog and serial peripherals cover most simple to moderately complex networked embedded designs without external glue logic. A key design consideration is supply decoupling. Place a 100 nF ceramic capacitor as close as possible to the VDD pin and a 10 uF bulk capacitor on the analog AVDD rail to keep ADC noise low. When the CAN bus is active, also respect the ISO 11898 transceiver layout guidance and use a dedicated CAN transceiver IC such as MCP2551.

An 8-bit microcontroller is a single-chip computing engine that executes instructions 8 bits at a time using a RISC (Reduced Instruction Set Computer) architecture. In the modern system hierarchy it sits below 32-bit MCUs and microprocessors and is widely used for deterministic, low-cost embedded control. The PIC18 family is Microchip's enhanced 8-bit tier - more capable than the PIC16 (more peripherals, more memory, linear program space) yet more cost-effective than a PIC24 or dsPIC, making PIC18F4480-I/P a typical middle-ground choice for connected industrial nodes. Key features of the PIC18F4480-I/P include 16 KB of self-programmable Flash with 100K endurance cycles per block, 768 bytes of SRAM, and 256 bytes of EEPROM for non-volatile parameter storage. The Enhanced CAN (ECAN) module supports CAN 2.0B active with multiple transmit/receive buffers - a feature that set this family apart at launch. Five CCP/ECCP modules provide PWM and capture/compare functions, and 10-bit A/D conversion is available on up to 13 channels. Architecturally, the PIC18F4480-I/P uses a modified Harvard structure with separate program and data paths plus a 16-bit instruction word, and nanoWatt Technology enables several low-power modes (Run, Idle, Sleep, deep Sleep, RTCC). Up to four hardware-accelerated multiply options and a hardware 8x8 unsigned multiplier in select instructions give it the throughput headroom to drive time-deterministic control loops. Typical applications include industrial automation and sensor networks over CAN bus, embedded automotive body controllers, building automation (HVAC, lighting, access control), low-cost USB/CAN bridges, and general-purpose 5V logic control boards where a through-hole DIP is preferred for prototype or rugged environments. When designing with this device, place decoupling 0.1 uF ceramic close to each supply pair, keep the ECAN bus termination (typically 120 ohm at each end) within a few millimeters of the CAN pins, and ensure the 40 MHz Fosc configuration in the configuration bits matches the oscillator hardware.

Typical applications include industrial sensing and control nodes, home appliances and white goods, low-cost consumer devices with character or graphical LCDs, automotive body electronics and LIN slaves, USB-to-serial bridges when paired with an external transceiver, and remote sensor / battery-powered data loggers that benefit from nanoWatt Technology. A key design consideration is selecting the right oscillator mode (HS, XT, or internal 31 kHz/8 MHz RC) early in the schematic phase, because switching modes after board layout typically requires re-tuning the oscillator loading capacitor values and clock-pll configuration bits. The MCU's regulator mode also requires a decoupling network on the ENVREG/VDDCORE pins.

PIC18F44J11-I/ML - 8-bit 48MHz 16KB Flash MCU | Microchip

The Microchip Technology PIC18F44J11-I/ML is a high-performance 8-bit PIC18J-series microcontroller featuring a 48 MHz internal clock (12 MIPS throughput), 16 KB of Flash program memory, 4 KB of SRAM, and 256 bytes of EEPROM, housed in a 44-pin QFN (8x8 mm) package. It integrates 10-bit A/D conversion, two analog comparators, two UART/USART, SPI, I2C, and USB-compatible full-speed peripheral interfaces, with Peripheral Pin Select (PPS) for flexible I/O mapping. An 8-bit microcontroller (MCU) is a programmable system-on-chip combining an 8-bit CPU core, non-volatile program memory, volatile data RAM, and a mix of digital and analog peripherals in a single silicon die. Within the broader semiconductor taxonomy, MCUs sit under embedded ICs -> microcontrollers -> 8-bit microcontrollers -> low-power nanoWatt family. The PIC18F44J11 belongs to the nanoWatt XLP (eXtreme Low Power) family, leveraging deep-sleep current draw in the nanoamp range to support battery-backed designs. Key differentiating features of the PIC18F44J11-I/ML include its wide 2.0V to 3.6V core voltage with 5.5V-tolerant I/O, Peripheral Pin Select remapping on most digital I/O, hardware Real-Time Clock/Calendar (RTCC) with dedicated timing crystal, and a 10-bit ADC with up to 13 input channels at 40 MHz conversion rate. The 44-QFN (8x8) package exposes 36 I/O pins with a small 8 mm footprint suitable for space-constrained USB-enabled embedded designs. The architecture uses a Harvard-class RISC-style pipeline, 16-bit instructions, and C-compiler-friendly orthogonal addressing. Hardware-level nanoWatt technology supports run, idle, and deep-sleep modes with wake-on-interrupt, making it appropriate for always-on sensor front-ends and human-interface devices. The 5.5V-tolerant I/O simplifies interfacing to legacy 5V peripherals without level shifters. Typical applications for the PIC18F44J11-I/ML include USB human-interface devices (HID), data loggers, USB-to-serial bridges, sensor front-ends with RTCC timestamping, motor drive control panels, and consumer appliance keypads. Its balance of 12 MIPS throughput, integrated USB 2.0 full-speed support, and nanoWatt low-power modes addresses cost-sensitive embedded designs that demand both real-time control and field longevity. A critical design consideration is the 5.5V-tolerant I/O paired with a 3.3V regulated core, which requires careful power-rail sequencing during in-circuit serial programming (ICSP). The deep-sleep current is enabled only when the internal regulator is configured for low-power mode via configuration bits, and wake sources must be explicitly enabled in firmware.

PIC18F44J11T-I/PT - 8-bit 48MHz 16KB Flash MCU | Microchip

The Microchip Technology PIC18F44J11T-I/PT is an 8-bit PIC microcontroller from the PIC18 J-series, featuring 16KB Flash program memory, 4KB RAM, and a 48 MHz internal clock speed (12 MIPS) in a 44-pin TQFP (PT) package. It operates from 2.0V to 3.6V (with 4.2V to 5.5V variant noted in legacy documentation) and integrates nanoWatt XLP power management for ultra-low-power applications. The device is engineered for cost-sensitive embedded designs requiring peripheral flexibility and small footprint. A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash/RAM/EEPROM), and programmable peripherals. The 8-bit PIC architecture uses a modified Harvard RISC design with separate program and data buses, enabling single-cycle instruction execution at the system clock. The PIC18 family extends the baseline PIC16 instruction set with 16-bit opcodes, larger linear memory addressing (up to 2 MB), and hardware multiply, positioning 8-bit PIC MCUs as low-cost workhorses for consumer, industrial, and IoT applications where 32-bit Cortex-M overhead is unnecessary. Key features of the PIC18F44J11T-I/PT include 36 I/O pins with Peripheral Pin Select (PPS) for flexible signal routing, a 10-bit ADC with up to 13 channels, two analog comparators, two CCP/ECCP modules, two USART, two MSSP (I2C/SPI), and Deep Sleep mode for sub-microamp standby current. The integrated RTCC and nanoWatt technology allow battery-powered designs to operate for years on a single cell. The 44-TQFP package (10x10 mm) provides ample I/O for human-machine interface and sensor-aggregation designs. Architecturally, the PIC18F44J11T-I/PT uses a 16-bit instruction word with 8-bit data path, executed at 48 MHz (12 MIPS instruction throughput). Internal oscillator accuracy is factory calibrated to +/- 2%. The device supports self-programmability via ICSP (In-Circuit Serial Programming), enabling firmware updates in the field without removing the chip from the board. Hardware CRC and a programmable 32-bit dead-man timer enhance system reliability in unattended deployments. Typical applications include low-power sensor nodes, home automation controllers, battery-powered remote controls, industrial telemetry modules, USB/HID peripherals, and small appliance control panels. Designers favor this MCU for its XLP sleep current (~20 nA typical in Deep Sleep) and mature MPLAB X IDE toolchain support. The wide peripheral mix eliminates the need for external ADC, comparator, or RTC chips in many designs. When designing with this device, verify that the 3.3V rail tolerance aligns with downstream sensors and that PPS reassignments are documented in the firmware header. Brown-out Reset (BOR) and Watchdog Timer (WDT) should be enabled by default for unattended installations. The Deep Sleep current draw of approximately 20 nA makes this MCU well suited for energy-harvesting or coin-cell designs.
