PIC18F6722-E/PT - 8-bit PIC MCU, 128KB Flash, 25MHz | Microchip

The Microchip Technology PIC18F6722-E/PT is an 8-bit PIC18 microcontroller featuring 128KB (64K x 16) of enhanced Flash program memory, 3,936 bytes of RAM, and a 64-pin TQFP (10x10 mm) package. It operates at up to 25MHz from a 4.2V to 5.5V supply, targeting large low-power (nanoWatt) and connectivity-rich embedded designs that require multiple serial interfaces and substantial on-chip memory. A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory, RAM, and multiple peripherals. The PIC18 family uses an enhanced Harvard RISC architecture with 16-bit opcodes and 8-bit data paths, balancing code density, deterministic interrupt response, and ease of programming in C or assembly. Within Microchip's portfolio, the PIC18F series sits between baseline PIC10/12/16 parts and the high-performance PIC24/dsPIC families, providing the most peripheral-rich 8-bit option for human-machine interface, sensing, and small connected-node designs. Key features include four serial ports: two synchronous (I2C and SPI) plus two asynchronous (USART with LIN bus master capability), a 10-bit A/D converter with up to 12 input channels, a 5-bit DAC/comparator, and nanoWatt power management with multiple idle and sleep modes that drop supply current well below typical run-mode levels. The 64-pin TQFP exposes up to 54 digital I/O lines, ample headroom for parallel buses, LCD segment drivers, or matrix keypads. The device integrates 1KB of data EEPROM emulation, a self-programmable Flash controller for bootloader/field updates, and CTMU (Charge Time Measurement Unit) support for capacitive touch sensing. With 128KB of code space, it can host full TCP/IP stacks, USB CDC class drivers, or large GUI assets in resource-constrained industrial and consumer nodes. Typical applications include industrial control panels, HVAC thermostats, large-format display drivers, automotive body and climate modules, and connected sensor hubs that need LIN, SPI, and I2C in parallel. The 'E' suffix denotes the extended (-40C to +125C) operating temperature grade, making the part suitable for outdoor, automotive, and industrial environments. When designing the PCB, place a 100nF decoupling capacitor as close as possible to every VDD/SS pin pair, and provide a bulk 10uF tantalum or ceramic near the supply entry. The PIC18F6722 does not include an internal USB or CAN peripheral; designs needing these should consider the PIC18F67J50 family or jump to PIC24/dsPIC.

It targets large low-power and connectivity applications that benefit from four serial ports (two MSSP for I2C/SPI and two enhanced USARTs with LIN support) plus 54 digital I/O pins. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path. It integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), EEPROM, timers, communication peripherals, and I/O on one die, and it occupies the lowest tier of the embedded compute hierarchy (8-bit MCU -> 16-bit MCU -> 32-bit MCU -> MPU). The PIC18F6722 belongs to the PIC18F8722 family, which is the highest-pin-count branch of the PIC18 enhanced flash family designed for human-machine interface, instrumentation, and connectivity nodes. Key differentiating features of the PIC18F6722-I/PT include 128KB self-programmable flash, 3,936 bytes of RAM, 1KB of EEPROM, a 10-bit ADC with up to 12 channels, two Capture/Compare/PWM modules, two 8-bit timers plus three 16-bit timers, and nanoWatt power management with multiple idle and sleep modes. The device operates from 4.2V to 5.5V across the industrial -40C to +85C range. Hardware multipliers and C-compiler-friendly architecture reduce firmware development time. The PIC18F6722's 64-pin TQFP and 80-pin TQFP variants share the PIC18F8722 family's pinout topology, giving engineers an upgrade path to higher pin counts or larger flash without PCB rework. Compared with smaller PIC18 members, the 6722 combines the deepest RAM in its class with the broadest peripheral mix. Typical applications include industrial control and HMI panels, automotive body and LIN nodes, home appliances with display/keypad interfaces, USB-to-UART gateways, and low-power sensor hubs that need four serial channels simultaneously. The wide supply range and large RAM also suit bootloader-based field-upgradeable products. Designers should budget for an external 10 MHz to 40 MHz crystal or resonator to drive the internal PLL-free oscillator chain, and provide decoupling close to every VDD/VSS pair. The ICD/ICSP pins (PGC/PGD) must remain accessible for in-circuit debugging. Pay attention to the 5V-only I/O when interfacing with 3.3V peripherals - a level translator or resistive divider is required. This page combines distributor stock and pricing as of 2026-09-28, drop-in TQFP-64 alternatives from Microchip's own portfolio, and practical design notes that go beyond the manufacturer datasheet to support faster component selection and second-sourcing.

PIC18F67J11-I/PT

PIC18F67J11-I/PT - 8-Bit 48MHz 128KB Flash MCU | Microchip TQFP-64

The Microchip Technology PIC18F67J11-I/PT is an 8-bit PIC® 18J family microcontroller running at 48 MHz (10 MIPS) with 128 KB of Flash program memory (64K x 16) and 3,936 bytes of RAM, packaged in a 64-pin TQFP (10x10 mm) industrial-grade (-40C to +85C) form factor. It integrates an internal 8 MHz oscillator, 51 digital I/O lines, and supports 1.8V, 2.5V, and 3.3V supply rails, making it suitable for AEC-Q100-style automotive and battery-powered designs that need wide voltage tolerance. Background: A PIC18 microcontroller is a Harvard-architecture 8-bit RISC MCU from Microchip's PIC18 family that uses a modified instruction set to balance code density and execution speed. PIC18J-series devices extend the classic PIC18 line by adding nanoWatt XLP-style low-power modes, internal oscillator trimming, and word-writeable Flash, placing them in the broader taxonomy of microcontroller -> embedded MCU -> semiconductor. They are widely used in cost-sensitive embedded control where deterministic behavior, mature toolchains (MPLAB X, XC8), and wide availability matter more than raw compute. Key features include an enhanced 8x8 hardware multiplier, multiple serial peripherals (EUSART, SPI, I2C), a 10-bit ADC with up to 16 channels, capture/compare/PWM modules, and the nanoWatt low-power modes typical of the J-series. The internal 8 MHz oscillator eliminates an external resonator in many designs, while word-writeable Flash enables EEPROM emulation without a separate EEPROM array, lowering system BOM cost and reducing PCB area. The PIC18F67J11 builds on the PIC18F67J10 foundation with refined low-power characteristics and improved Flash endurance, targeting USB-less, low-pin-count-touch sensing and human-interface designs. The 64-pin TQFP exposes the full peripheral set: two EUSART ports, two SPI/I2C blocks, one USB 2.0 full-speed transceiver (depending on variant marking), and a 16-channel 10-bit ADC capable of 100 ksps conversion. Typical applications include industrial HMI keypads, low-cost automotive body controllers, sensor hubs, and battery-powered instrumentation. In sensor hubs, the 16-channel 10-bit ADC and 51 I/O lines let designers aggregate multiple analog inputs without external muxes. For automotive body controllers, the wide 2.0V to 3.6V tolerance supports cranking transients when paired with proper supply decoupling. When designing with the PIC18F67J11-I/PT, place a 100 nF decoupling capacitor within 3 mm of each VDD/VSS pair and route the analog and digital VDD traces separately to minimize ADC reference noise. Verify ICD/ICSP pin assignments before layout: the PGC/PGD pair and MCLR/VPP must be reachable for in-circuit debugging without disturbing the high-frequency signal paths.

PIC18F67J11T-I/PT - 128KB Flash 8-bit MCU 48MHz TQFP-64 | Microchip

The Microchip PIC18F67J11T-I/PT is a high-performance 8-bit PIC18J family microcontroller delivering 48 MHz / 12 MIPS performance, 128 KB Flash program memory and 3936 bytes of RAM, housed in a 64-pin TQFP (10x10 mm) package with 0.50 mm pitch and tape-and-reel packaging. The 'T' suffix denotes T&R while '-I/PT' indicates the -40C to +85C industrial temperature grade. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, Flash program memory, SRAM data memory, peripherals (ADC, timers, UART, I/O), and oscillator onto one die. PIC18J devices sit in the mid-tier of Microchip's 8-bit PIC lineup, bridging the PIC16 baseline and the PIC32 32-bit family, and they target cost-sensitive embedded designs that need more code space and peripheral count than a PIC16 can provide. Key features include a 2.0 V to 3.6 V single-supply operating range, 5 V-tolerant digital inputs, 51 digital I/O pins, a Parallel Master Port (PMP), a 10-bit ADC, two analog comparators, four 16-bit timers, two UART/SPI/I2C capable EUSART modules, and nanoWatt power management with multiple low-power sleep modes. The enhanced In-Circuit Debugger (ICD) provides three hardware breakpoints, accelerating firmware bring-up on MPLAB Xpress and MPLAB Snap/MPLAB X IDE tool chains. Flash endurance is rated at 10,000 erase/write cycles with 20-year data retention. Architecturally, the PIC18J core uses a 16-bit instruction word with 8-bit data path, a 31-level hardware stack, hardware multiply, and direct/indirect addressing modes - giving PIC16-source compatibility plus C-compiler friendliness through the XC8 toolchain. The 48 MHz oscillator (with on-chip PLL) yields a 12 MIPS instruction throughput with 200 ns minimum instruction cycle. Typical applications include industrial control panels, automotive body/HMI modules, consumer appliances, USB-embedded peripherals (via the PIC18 USB derivatives), graphical LCD controllers using the PMP, and sensor-hub front-ends. The 5 V tolerant inputs simplify interfacing to legacy 5 V logic. When designing, observe the 3.3 V supply constraint - although inputs are 5 V tolerant, the core runs from 2.0-3.6 V, so most designs use an LDO such as MCP1700 from a 5 V rail. Decouple VDD/VSS with 100 nF plus 1 uF ceramic capacitors placed within 3 mm of the pins.

The Ethernet peripheral is the defining element: it eliminates the need for an external PHY or MAC chip, reducing BOM cost and PCB area in remote-monitoring nodes. Internally, the part uses a Harvard RISC core with a hardware multiplier, runs from an internal 8 MHz oscillator (pll-able to 41.667 MHz), and supports in-circuit programming via ICSP. The Flash and configuration bits are accessed through Microchip's standard MPLAB development flow, and the on-chip Ethernet module uses an internal DMA engine to offload packet handling from the CPU. Typical applications include Industrial Automation (Modbus/TCP nodes, sensor gateways), Building Automation (BACnet/IP thermostats, lighting controllers), Remote Monitoring (utility metering, asset tracking), Embedded Web Servers, and Home Appliance Networking. The wide 4.2 V to 5.5 V supply range also makes it tolerant of unregulated 5 V wall adapters. When designing with this part, ensure the integrated Ethernet PHY is matched to a 1:1 isolation transformer and RJ45 with HP Auto-MDIX wiring to preserve the auto-crossover feature. The 64-pin TQFP footprint requires careful PCB routing of the differential Ethernet pair to maintain 100-ohm differential impedance over a continuous reference plane.

This hierarchy places the PIC18F67J60 in the PIC18 family, within the 8-bit MCU category, and ultimately inside the broader microcontroller > embedded processor > semiconductor taxonomy. Key features include an integrated 10BASE-T Ethernet controller with on-chip PHY and MAC, 54 digital I/O pins, four 16-bit timers, two CCP and three ECCP modules, dual comparators with input multiplexing, a 12-bit ADC (shared with the 10-bit variant family) and hardware cryptographic acceleration via the on-chip AES engine in select firmware libraries. The 128KB Flash supports self-programming and ICSP, and 3.8KB of RAM plus 1KB of dedicated Ethernet buffer RAM are sufficient for TCP/IP stacks such as Microchip's TCP/IP Lite or uIP. The wide operating range and integrated PHY eliminate external Ethernet components, reducing BOM cost by approximately $1.50 per node. Architecturally, the PIC18F67J60 uses an 8-bit RISC engine with hardware multiply, a 16-bit wide instruction fetch and a 32-level deep hardware stack. The integrated Ethernet block follows IEEE 802.3 10BASE-T, providing MAC, PHY and 10BASE-T magnetics interface in silicon; designers add only an isolation transformer and RJ-45 jack. The internal 2.5V LDO allows single-supply 3.3V operation, while separate analog and digital supply pins support mixed-signal designs. Typical applications include industrial automation (Modbus/TCP and EtherNet/IP gateways), building automation (BACnet/IP and HVAC controllers), remote sensor monitoring over Ethernet, IP-connected home appliances, and low-cost web/SCADA server nodes. Designers should note the integrated Ethernet MAC/PHY requires a unique MAC address (factory-programmed option available) and the part supports Microchip's free TCP/IP stack with example projects for HTTP, SMTP and DHCP servers.

The device integrates a 12-bit A/D converter with up to 16 channels, multiple communication peripherals (UART, SPI, I2C), and a Charge Time Measurement Unit (CTMU) for capacitive touch sensing and precise time measurement. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, I/O peripherals, and interrupt logic. The PIC18F family sits within the broader 8-bit PIC microcontroller hierarchy from Microchip, occupying the high-performance tier above the PIC16 and baseline PIC10/12/14 families. XLP technology is a suite of power-management modes (including nanoWatt XLP sleep currents down to 300 nA) that make this MCU well suited to battery-powered and energy-harvesting applications where quiescent draw dominates battery life. Key differentiating features include 64 MHz maximum clock speed (with a 16 MIPS instruction throughput at that rate), 53 digital I/O pins, a 12-bit A/D converter capable of up to 100 ksps, two analog comparators, a 16-bit timer/counter module with PWM, and CTMU hardware for touch and time-of-flight measurements. The wide operating voltage range of 1.8 V to 5.5 V supports both 3.3 V and 5 V system designs without external level translation. The PIC18F67K22-I/PT is the industrial temperature grade (-40C to +85C) variant in the 64-pin TQFP package. Architecturally, the device uses an enhanced Harvard architecture with separate program and data buses, a 16-bit instruction set, and hardware multiplier for faster arithmetic than baseline PIC cores. The integrated nanoWatt XLP modes (Run, Idle, Sleep, and RTCC) and the RTCC module (with dedicated 32 kHz crystal support) provide fine-grained control over active and standby power budgets. Brown-out Reset (BOR), Watchdog Timer (WDT), and Power-on Reset (POR) hardware ensure reliable start-up in noisy industrial environments. Typical applications include capacitive touch user interfaces, battery-powered sensor nodes, industrial control panels, low-power metering, USB device peripherals (using the 8-bit USB-capable sibling PIC18F46K22 or external transceiver), automotive body electronics (with the extended-grade variant), and embedded HMI displays. The CTMU peripheral simplifies capacitive touch button and slider implementations by measuring charge time rather than requiring an external timer IC. When designing with this part, pay attention to the in-circuit serial programming (ICSP) pins and provide a robust decoupling network (100 nF + 10 uF near VDD) to keep the analog and digital rails clean. The 64-pin TQFP footprint is shared with many PIC18F siblings, allowing in-package migration to PIC18F87K22 or down-migration to PIC18F47K22 with minimal PCB rework.

It operates at up to 64 MHz instruction rate (16 MIPS) from a 1.8V to 5.5V supply and integrates a 12-bit A/D converter with up to 16 channels, multiple communication peripherals, and the Charge Time Measurement Unit (CTMU) for capacitive touch sensing. What is a PIC18 microcontroller? The PIC18 family is Microchip's high-performance 8-bit RISC architecture line, optimized for low power, robust peripherals, and a long product lifecycle, sitting above the baseline PIC16 and PIC12 families in Microchip's 8-bit portfolio. XLP (eXtreme Low Power) nanoWatt technology refers to a set of clocking, sleep mode, and peripheral gating techniques that allow sleep currents in the nanoamp range while retaining RAM and fast wake-up for battery-powered and energy-harvesting applications. Key features include the nanoWatt XLP sleep current of approximately 20 nA, an active current of about 8 mA at 64 MHz, a CTMU peripheral for capacitive touch and precise time measurement, an Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), two MSSP ports for SPI/I2C, multiple 16-bit timers, capture/compare/PWM modules, and a 12-bit A/D converter with up to 16 channels. The part also supports self-programming and an integrated LCD driver option on related die variants. Technically, the PIC18F67K22 family uses a modified Harvard architecture with a 16-bit instruction word and 8-bit data path, executed through a 2-stage pipeline at 4 clock cycles per instruction. Internal oscillator options support 16 MHz to 64 MHz operation with PLL, providing clock accuracy suitable for UART communication without external crystals in many designs. The wide 1.8V-5.5V supply range enables direct operation from Li-Ion or two AA cells in portable designs. Typical applications include capacitive touch user interfaces with the CTMU, battery-powered remote sensors with nanoWatt XLP, industrial control panels with 12-bit measurement, USB-enabled human interface devices when paired with an external transceiver, LCD-based consumer appliances, and automotive body/comfort modules using the wider PIC18 K-series derivatives. When designing with this device, ensure proper decoupling with a 100 nF ceramic capacitor close to each VDD pin and a bulk capacitor on the regulated rail. The CTMU requires careful PCB layout and a reference current calibration step for accurate capacitive touch readings, and unused I/O pins should be configured as outputs low to minimize quiescent current.
