PIC18F6628T-I/PT - 96KB Flash 8-bit MCU, 64-Pin TQFP | Microchip

The Microchip Technology PIC18F6628T-I/PT is an 8-bit RISC microcontroller in the PIC18F high-performance family, integrating 96 KB of Flash program memory, 4 KB of SRAM, and 1 KB of data EEPROM in a 64-pin TQFP package. It executes instructions at 40 MHz (10 MIPS) with a 200 ns instruction cycle, and operates from 4.2 V to 5.5 V across the industrial -40C to +85C range. The device exposes 54 digital I/O pins, 12 channels of 10-bit ADC, two USART, one MSSP (SPI/I2C), and a parallel slave port for external bus expansion. Background Knowledge: An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, peripherals, and I/O on one die. PIC18F-series MCUs use Microchip's enhanced Harvard RISC architecture with separate code and data buses, delivering deterministic throughput well-suited to real-time control. Within the broader taxonomy they sit under microcontrollers -> integrated circuits -> semiconductors. Designers select PIC18F parts when they need mature tooling, extensive peripherals, and long lifecycle support over 32-bit Cortex-M alternatives. Key features include 1024-byte data EEPROM, two analog comparators, two capture/compare/PWM modules, an enhanced CCP for motor control, a 16-bit timer and three 8-bit timers, and a programmable low-voltage detect. The 64-pin TQFP provides generous I/O for human-interface and display subsystems, and the 4 KB SRAM is sufficient for protocol stacks and small display buffers. Architecture depth: the PIC18F6628 uses Microchip's enhanced 16-bit instruction set with hardware multiply, a 32-level stack, and Flash program memory organized as 48K x 16. Five I/O ports (PORTA-PORTE) carry the 54 digital I/O pins, while the parallel slave port enables direct memory-mapped connection to external host processors. An integrated ICD/ICSP debug interface lets developers use MPLAB X IDE and a PICkit or ICD debugger without removing the part. Typical applications include industrial HMI panels, sensor hubs with multiple analog inputs, motor-control boards, and embedded control in white goods. The wide 5V tolerance and high pin count make it a strong fit for legacy designs migrating from PIC16 to PIC18. Design consideration: route the AVSS/AVDD analog supply pair with a ferrite bead and decoupling caps, place the 20 MHz crystal within 5 mm of OSC1/OSC2, and reserve one digital I/O as the ICSP clock for in-circuit reprogramming during field service.

The Microchip Technology PIC18F66J50-I/PT is a high-performance 8-bit PIC18 microcontroller featuring an integrated Full-Speed USB 2.0 transceiver, 64 KB of Flash program memory and 3,936 bytes of RAM, housed in a 64-pin TQFP (PT) package measuring 10x10 mm with 1.0 mm height. It executes instructions in 200 ns (up to 16 MIPS at 48 MHz) and is part of the PIC18F87J50 family engineered for low-power nanoWatt and connectivity applications. Key features include FS-USB at 12 Mbit/s, an MI2C port, an SPI port up to 10 Mbit/s, and two asynchronous EUSART channels that support LIN bus, along with 54 digital I/O pins and a 10-bit ADC. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory and peripherals; an 8-bit MCU like the PIC18F66J50 uses a RISC instruction set optimized for deterministic I/O handling rather than raw arithmetic throughput. Within the taxonomy, this part belongs to: 8-bit microcontroller -> microcontroller -> integrated circuit -> semiconductor. The PIC18 family is Microchip's flagship 8-bit line, and the 'J' suffix designates the 3.3V-core Flash families that still operate from a 4.2-5.5V supply for USB compatibility. Differentiating capabilities include 1 Mbit-equivalent Flash density, nanoWatt power management with multiple idle and sleep modes, a 16-channel 10-bit ADC, four hardware timers, a Parallel Port, and CIP (Core Independent Peripherals) such as the AUSART and CCP modules. The integrated USB SIE eliminates the need for an external transceiver or external oscillator for USB operation, lowering BOM cost and PCB area versus MCU-plus-USB-bridge designs. Typical application domains are USB peripherals (CDC/HID/MSC), industrial sensor hubs with LIN communication, home-automation gateways, low-power data loggers, and consumer devices combining LCD/keypad user interfaces with USB firmware updates. Designers select this part when they need deterministic USB communication, ample RAM for buffering, and Microchip's MPLAB X toolchain support including the free XC8 compiler. Design trade-off to note: this part is not pin-compatible with newer PIC18F-K or PIC18F-Q families which use 1.8-5.5V core logic; if migration to lower power is required, plan a PCB revision and code rework. The 'I' suffix denotes the industrial -40C to +85C operating range.

The 'J' suffix denotes the 2.0 V to 3.6 V core-voltage family optimized for nanoWatt power-saving modes. What is a PIC18J microcontroller? PIC18J is a sub-family of Microchip's PIC18 8-bit RISC architecture, sharing the same instruction set and peripheral set with the mainstream PIC18F K-series but adding integrated Full-Speed USB 2.0 and operating from a lower 2.0 V core supply. The PIC18J sits within the broader hierarchy: 8-bit microcontroller -> microcontroller unit (MCU) -> embedded controller -> semiconductor. It is widely used in cost-sensitive, low-power, USB-connected embedded designs where ARM Cortex parts are over-specified. Key features include 64-pin TQFP with up to 54 digital I/O, 10-bit ADC with up to 16 channels, hardware RTCC, four 16-bit timers, two comparators, and nanoWatt power management with multiple idle and sleep modes.

PIC18F66J60T-I/PT - 8-bit MCU, 64KB Flash, Ethernet, 64-TQFP | Microchip

The Microchip PIC18F66J60T-I/PT is an 8-bit PIC18 microcontroller featuring an integrated 10Mbps Ethernet MAC+PHY peripheral, 64KB of Flash program memory (32K x 16), and 3808 bytes of RAM. The device operates from a 2.0V to 3.6V core supply (with 4.2V to 5.5V I/O tolerance on selected pins via internal charge-pump regulation), at a maximum clock rate of 41.667MHz (10MIPS), and is housed in a 64-pin TQFP (10x10 mm) package. It is part of the PIC18F "J" family which combines single-cycle instruction execution with on-chip networking peripherals. A microcontroller (MCU) is a single-chip processing unit integrating a CPU core, program memory (Flash), data memory (RAM), and configurable peripherals. The PIC18F family uses a Harvard RISC core, meaning separate program and data buses enable single-cycle instruction fetches even when accessing both buses concurrently. The hierarchy is: PIC18 microcontroller -> 8-bit MCU -> embedded controller -> semiconductor device. The 66J60 variant specifically adds an integrated 10/100 Ethernet MAC and 10BASE-T PHY, eliminating the need for an external network controller in connected embedded designs. Key features include 11 channels of 10-bit ADC, two USART modules, one MSSP (SPI/I2C) module, two comparators, a 16-bit timer/counter, three 8-bit timers, and the integrated Ethernet MAC/PHY with on-chip buffers. The device also has a nanoWatt power-managed operating mode for battery-friendly sleep states, and supports In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD) for development. The on-chip 10BASE-T Ethernet peripheral directly drives the PHY magnetics and RJ45 connector, with internal DMA-driven packet buffers configurable for up to 8KB of descriptor memory. The 41.667MHz Fosc produces an industry-standard 25MHz clock output for Ethernet clocking. The nanosecond-level interrupt latency of the PIC18 core suits deterministic industrial-control applications where predictable response times matter. Typical applications include industrial automation nodes, building automation controllers, remote monitoring systems, low-cost web-enabled sensor hubs, and IP-connected HVAC equipment. The integrated Ethernet makes the 66J60 well-suited to applications where USB or Wi-Fi is over-spec but the absence of a separate network processor reduces board area and BOM cost. Operating voltage of 2.0V to 3.6V lets it run from a 3.3V rail or 2xAA cells with a boost converter. When designing with this part, allocate 3.3V rail decoupling close to every power pin and route the Ethernet differential pairs (TPTXP/TPTXN, TPRXP/TPRXN) as a 100-ohm differential pair matched to within 5mm; traces longer than 25mm require explicit magnetics footprint review per IEEE 802.3. Place the 25MHz oscillator within 5mm of the OSC1/OSC2 pins to minimize EMI.

PIC18F66K22-I/MR

PIC18F66K22-I/MR - 64KB Flash 8-bit MCU, 64MHz, 64-VQFN | Microchip

The Microchip Technology PIC18F66K22-I/MR is an 8-bit PIC18 microcontroller with 64KB of Flash program memory, 4KB of RAM, and 1KB of EEPROM, operating at up to 64MHz across a 2.5V to 5.5V supply range in a 64-pin VQFN (9x9 mm) package. It is part of the PIC18F "K22" family of enhanced-flash MCUs that integrate nanoWatt XLP extreme-low-power technology, a 12-bit ADC with up to 16 channels, and a Charge Time Measurement Unit (CTMU) for capacitive-touch sensing. A PIC18F-series microcontroller is a modified-Harvard 8-bit RISC MCU built around a 16-bit instruction word and an 8-bit data path, optimised for high code density, deterministic interrupt latency, and low power consumption. PIC18 devices sit between simple PIC16/12 controllers and the higher-performance dsPIC/PIC32 lines in the Microchip portfolio, and are typically deployed as main system controllers in cost-sensitive, low-power embedded designs spanning consumer white goods, industrial sensors, and automotive body electronics. Key features include nanoWatt XLP sleep currents below 100 nA typical, a 12-bit A/D converter with up to 16 input channels, multiple Enhanced USART, SPI, and I2C peripherals, a 16-bit Capture/Compare/PWM module, and an RTCC with independent clocking. The CTMU peripheral enables robust capacitive touch buttons, sliders, and proximity sensing using only a few external passive components. The 64-pin VQFN package exposes up to 54 digital I/O lines for parallel expansion and user-interface needs. The device uses Microchip's enhanced Flash cell technology and supports self-programmability under firmware control, plus background-debug MPLAB ICD support through two interface pins. Internal oscillator blocks (HFINTOSC up to 16 MHz and LFINTOSC at 31 kHz) allow operation without an external crystal, while a Phase-Locked Loop (PLL) is available to derive the 64 MHz system clock from internal or external sources. The architecture also integrates a 5-bit DAC, multiple comparators, and hardware CRC for data integrity. Typical applications include capacitive-touch user interfaces for white goods and consumer appliances, low-power battery-driven sensor nodes with sleep duty cycling, industrial control panels with mixed analog and digital I/O, and automotive body modules requiring AEC-style robustness under extended temperature. The wide 2.5V-5.5V supply range also makes the part suitable for both 3.3V and 5V system rails. When designing with this MCU, plan for a low-impedance ground return and decoupling of VDD/AVDD pairs within 5 mm of the respective pins. Engineers should also evaluate the RTCC current budget against their standby lifetime target, since the XLP sleep-current figure dominates battery-life calculations.
