PIC18LF1320T-I/SS

PIC18LF1320T-I/SS - 8KB Flash 8-bit MCU 40MHz SSOP-20 | Microchip

The Microchip Technology PIC18LF1320T-I/SS is an 8-bit RISC microcontroller from the PIC18 family featuring 8KB of Flash program memory, 256 bytes of RAM and a 40 MHz CPU core, supplied in a 20-pin SSOP package. The 'LF' prefix indicates the low-voltage F-variant supporting operation across 2.0V to 5.5V, while the 'T' suffix designates the tape-and-reel packaging option and 'I/SS' indicates the industrial temperature range (-40C to +85C) in SSOP-20. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory and peripheral interfaces, and the PIC18 family is Microchip's baseline 8-bit RISC architecture built around a Harvard-class core with 16-bit instructions delivering 200 ns execution per instruction. Low-dropout 'LF' variants extend battery-powered design reach by enabling supply voltages from 2.0V up through the conventional 5.5V rail, allowing the same silicon to operate from a single Li-ion cell, two AA cells, or a regulated 3.3V/5V system rail. Key features of the PIC18LF1320T-I/SS include 8KB of in-circuit serial programmable Flash (good for 1000 erase/write cycles), 256 bytes of data RAM, 256 bytes of EEPROM, 16 I/O pins, an internal oscillator, an enhanced CCP module, a 10-bit ADC with up to 7 channels, and nanoWatt power-managed modes that drop quiescent current to microamp levels during standby. Internal peripherals include a USART, an MSSP (for SPI/I2C), multiple timers, and a watchdog timer for safety-critical applications. Architecturally, the device uses a 16-bit wide instruction word and an 8-bit data path, with a 31-level hardware stack for subroutine handling. The 40 MHz oscillator yields a 10 MIPS instruction throughput, and the Flash can be programmed via ICSP without removing the part from the board. Together with the wide 2.0V-5.5V supply and 16 I/O lines, the part is well suited to compact battery-powered, sensor, and consumer control designs. Typical applications include battery-powered sensor nodes, small consumer appliances, automotive interior lighting modules, USB peripherals (using the USART bit-banged with external transceiver), simple motor control via the ECCP, and industrial white-goods control panels. The combination of 8KB Flash, 256B RAM, and nanoWatt sleep current makes the device particularly well matched to size- and cost-constrained nodes that need more code space than an 8-pin PIC10/12 can offer. When designing with this part, follow Microchip guidance on decoupling (place a 0.1 uF ceramic as close to VDD/VSS as possible), MCLR reset pull-up, and ICSP programming pin allocation. The wide operating voltage provides headroom, but designers should still budget for the internal oscillator accuracy across the industrial temperature range when used for asynchronous serial communication.

PIC18LF14K22T-I/SS - 8-bit 16KB Flash XLP MCU 20-SSOP | Microchip
PIC18LF14K22T-I/SS

PIC18LF14K22T-I/SS - 8-bit 16KB Flash XLP MCU 20-SSOP | Microchip

The Microchip Technology PIC18LF14K22T-I/SS is an 8-bit PIC18 family CMOS flash microcontroller based on the nanoWatt XLP (eXtreme Low Power) architecture, delivering up to 16 MIPS through a C-compiler-optimized RISC core. Housed in a 20-pin SSOP package, this LF variant supports a wide 1.8V to 3.6V operating range, distinguishing it from the standard 'F' sibling which operates from 2.3V to 5.5V. Key headline parameters are 16 KB Flash program memory, 512 bytes of SRAM, 256 bytes of data EEPROM, and a 64 MHz internal oscillator. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals on one silicon die. The PIC18 family sits in the 8-bit hierarchy above baseline PIC10/12/16 parts, offering enhanced peripherals, C-compiler-friendly architecture and Harvard-bus design; this places it within the broader taxonomy of microcontroller -> embedded processor -> semiconductor. nanoWatt XLP technology is Microchip's low-power brand, providing deep-sleep currents in the nA range for battery-friendly designs. Differentiating features include 17 channels of 10-bit ADC, an enhanced USART, two SPI/I2C modules, an on-chip 16-level voltage reference, a comparator module, and a mTouch capacitive-touch peripheral. The internal 16 MHz and 64 MHz oscillators eliminate external crystals in many designs, and the device supports in-circuit serial programming (ICSP) via two pins. Watchdog timer, brown-out reset, and low-voltage detection are integrated. Architecturally, the PIC18LF14K22 uses a Harvard design with separate program and data buses, a 16-bit instruction word, and a hardware multiply routine. The 'LF' (low-voltage Flash) prefix indicates a true 1.8V minimum Vdd, and the 'I' suffix denotes the industrial -40C to +85C operating range. Tape-and-reel ('T') and SSOP package options support automated high-volume assembly. Typical applications include battery-powered sensor nodes, wearable health monitors, remote controls, capacitive-touch user interfaces, IoT edge devices, and low-power industrial instrumentation. The deep-sleep nanoWatt XLP mode and 1.8V minimum Vdd allow operation directly from a single lithium coin cell, with quiescent currents in the nA range during sleep. A key design consideration: ensure your firmware uses the LF-specific configuration bits (the LF silicon revises some internal regulator settings versus the 'F' part) and validate ADC performance at the lower Vdd bound of 1.8V, where reference stability may differ from 3.3V operation. This page consolidates real-time distributor pricing, drop-in package-equivalent alternatives, and application-specific design notes that go beyond the manufacturer datasheet narrative, providing actionable selection guidance for engineers and procurement teams.

PIC18LF14K50-I/MQ

PIC18LF14K50-I/MQ - 8-bit USB MCU 16KB Flash 48MHz | Microchip

The Microchip Technology PIC18LF14K50-I/MQ is an 8-bit PIC18 RISC microcontroller featuring 16 KB (8K x 16) of Flash program memory, 768 bytes of RAM, and an integrated full-speed USB 2.0 compliant device peripheral, housed in a 20-pin VQFN (5x5 mm) exposed-pad package. It operates at up to 48 MHz across a 2.7 V to 3.6 V supply range, making it the low-voltage (LF) variant suited for battery and XLP nanoWatt applications. The part is qualified for the industrial -40C to +85C temperature range and ships in the -I/MQ speed/grade suffix. An 8-bit microcontroller (MCU) is a microprocessor core with an 8-bit data bus, on-chip Flash for program storage, RAM for working data, and integrated peripherals such as timers, ADC, communication interfaces, and interrupt controllers. Within the embedded hierarchy, MCUs sit below microprocessors and above discrete logic: 8-bit MCU -> microcontroller -> embedded controller -> semiconductor IC. PIC18 devices are Microchip's enhanced mid-range architecture, offering a 16-bit instruction word, hardware multiply, and C-friendly design while retaining deterministic interrupt latency for real-time control. Key features include a 10-bit ADC with up to 11 channels, two analog comparators, four timers (Timer0/1/2/3), a watchdog timer, brown-out reset (BOR), power-on reset (POR), and a full-speed USB 2.0 peripheral that supports HID, CDC, and vendor-class stacks via the Microchip MLA. The on-chip 3.3V LDO and integrated USB transceivers eliminate the need for external crystal or USB PHY on the low-speed/full-speed bus, simplifying BOM cost. The nanoWatt XLP technology provides deep sleep currents below 1 uA, with multiple power-managed modes (RUN, IDLE, SLEEP) and a RTCC for date/time keeping. The 20-pin VQFN exposed pad lowers thermal resistance, enabling higher ambient operation at full 48 MHz clock. Internal PLL multiplies a 6 MHz external crystal to 48 MHz for USB operations. Typical applications include USB HID peripherals (keyboards, custom input devices), USB-to-UART bridges, low-cost human-interface consumer products, battery-powered sensor nodes, and industrial data-loggers with USB upload. The wide 2.7-3.6V range plus XLP sleep modes enable multi-year coin-cell operation. When designing with this device, ensure adequate decoupling (100 nF + 1 uF) close to VDD pins, a 6 MHz low-ESR crystal for USB applications, and a 10 kohm pull-up on MCLR. Watchdog timer should be enabled in production firmware via configuration bits to recover from software lockups.

The XLP nanoWatt technology enables standby currents as low as [DATA_NEEDED: standby current value] nA, making it ideal for battery-powered designs. Wide operating voltage spans 1.8V to 3.6V (LF variant). The architecture pairs a RISC CPU core with hardware USB, eliminating external PHY requirements. Internal oscillator options, including the 31kHz to 16MHz HFINTOSC and 31kHz LFINTOSC, support USB clocking from the internal 48MHz source. Self-programmability via ICSP and CTMU for capacitive touch round out the peripheral set. Typical applications include USB-to-UART bridges, HID peripherals (keyboards/mouse/joysticks), low-cost USB sensor dongles, USB chargers and portable data loggers. Designers favor this part for its compact 20-pin footprint, integrated USB, and Microchip's free MPLAB X toolchain. Design consideration: USB requires precise 48MHz clocking; for low-power sleep modes the LF variant (1.8V min) is essential. Decouple VDD with 100nF ceramic near each VDD pin and route D+/D- as a 90-ohm differential pair.
