PIC16LF1459-E/SS

PIC16LF1459-E/SS - 14KB Flash 8-bit MCU, 48MHz, USB, XLP | Microchip

The Microchip Technology PIC16LF1459-E/SS is an 8-bit PIC microcontroller built on the enhanced mid-range PIC16 core, delivering 48 MHz (12 MIPS) performance from 14 KB of self-programmable Flash, 1024 bytes of RAM, and a 20-pin SSOP package. It features a 14-channel 10-bit ADC, a 5-bit DAC, two PWM modules, a comparator, and a full-speed USB 2.0 transceiver with on-chip 3.3V regulator, which is uncommon in this memory class. An 8-bit PIC microcontroller is a Harvard-architecture RISC processor optimized for low-power embedded control. The PIC16 family sits in the middle of Microchip's product hierarchy (PIC10/12/16/18/24/dsPIC33), offering more peripherals and memory than baseline PIC12 parts while retaining the XLP (eXtreme Low Power) sleep-current advantage over higher-end dsPIC33 devices. The LF prefix denotes a 1.8V-3.6V wide-voltage core, enabling direct battery operation from a single Li-ion or two alkaline cells. Key specifications include 1.8V to 3.6V VDD operation, 49 nA typical sleep current with full RAM retention, USB 2.0 full-speed (12 Mbps) device support without an external transceiver, and a 10-bit ADC reaching up to 100 ksps across 9 source channels. The SSOP-20 footprint at 0.65 mm pitch keeps the part footprint-compatible with PIC16LF1454/1455/1458 family siblings, easing PCB reuse across product variants. Architecturally, the device pairs a hardware multiplier with a single-cycle 8x8 MAC and an in-circuit debug interface, while the internal 48 MHz HFINTOSC eliminates external crystals in cost-sensitive USB nodes. The CIP (Core Independent Peripheral) set - including the CWG, NCO, and PWM - allows event-driven responses without CPU intervention, lowering average current in sensor and human-interface designs. Typical applications include USB HID peripherals, e-cigarettes and vape controls, wireless sensor dongles, IoT bridges, and consumer touch interfaces. The wide-voltage range and 14 KB of Flash comfortably fit CDC + vendor-class composite USB stacks plus application logic on a single die. When designing with this part, remember that the internal USB voltage regulator requires a 200-ohm resistor on VUSB3V3 and a decoupling capacitor to ground; omitting either breaks USB enumeration. Decouple VDD with at least 100 nF close to the pin to keep ADC noise low. This page synthesizes distributor pricing, drop-in alternative MPNs, and design guidance beyond the manufacturer datasheet, helping engineers compare sources and apply the part correctly in USB and battery-powered designs.

The XLP technology offers nanoWatt sleep currents and active current in the microamp range, enabling coin-cell and battery-backed designs. The device uses an enhanced mid-range PIC16 core with a Harvard RISC architecture, executing most instructions in a single 200 ns cycle (at 20 MHz) or 83 ns at 48 MHz. The integrated 48 MHz high-speed internal oscillator (HFINTOSC) eliminates the need for an external crystal in many USB designs, while the integrated 3.3V regulator provides internal core power from a single supply rail. Typical applications include USB HID peripherals such as keyboards, mice, and custom input devices, USB-to-UART bridges, low-power sensor nodes, consumer electronics requiring USB connectivity, and battery-powered embedded products where PCB area is constrained. The UQFN-20 (4x4 mm) package with exposed pad makes it ideal for space-constrained wearables and handheld designs. When designing with this part, place a 0.1 uF decoupling capacitor close to VDD, provide a solid ground plane, and solder the exposed pad to a thermal copper pour for best electrical and thermal performance. The USB D+/D- lines should be routed as a 90-ohm differential pair with controlled impedance, and consider ferrite beads for EMI-sensitive applications. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone manufacturer datasheet, providing engineers and procurement teams with a single, citable reference for the PIC16LF1459-I/GZ.

The device combines the enhanced mid-range PIC16 core with 200 ns instruction execution and an XLP (eXtreme Low Power) design that targets battery-conscious embedded systems. An 8-bit PIC microcontroller is a Harvard-architecture RISC processor that executes one instruction per cycle (excluding branches) with separate program and data buses. The PIC16F14xx family extends this baseline with USB 2.0 full-speed transceivers, configurable logic cells, and dual PWM/capture modules, positioning the line between simple 8-bit controllers and larger 16-bit dsPIC devices. Within the broader taxonomy, PIC16F145x sits in the family 8-bit microcontroller -> RISC MCU -> embedded controller -> semiconductor, serving as a low-cost workhorse for human-interface and consumer products. Key features of the PIC16LF1459 include 18 general-purpose I/O pins, 4 timers, 2 PWM channels, 2 comparators, an 8-channel 10-bit ADC, a watchdog timer with its own dedicated oscillator, an internal oscillator, and on-chip USB with a dedicated 3.3V regulator. XLP technology keeps active current in the milliampere range and sleep current under typical microampere values, which is critical for USB-powered or battery-powered designs. Typical applications for the PIC16LF1459-I/SS are USB human-interface devices such as keyboards, mice, game controllers, USB-to-UART bridges, and low-cost sensor/LED peripherals. Designers select this part when they need a true USB device on a 20-pin footprint without external PHY, and when power budget, BOM size, and a mature toolchain (MPLAB X, XC8) are top priorities. When designing in this part, plan the 5V/3.3V domains: the USB transceiver is 3.3V-tolerated and the part includes an internal 3.3V regulator that can supply the pull-up resistor. A 1 uF decoupling capacitor near VDD and proper PCB stackup for the D+/D- differential pair are essential for USB compliance.

PIC16LF1459T-I/GZ

PIC16LF1459T-I/GZ - 8-Bit USB MCU, 14KB Flash, 48MHz, 20-UQFN | Microchip

The Microchip Technology PIC16LF1459T-I/GZ is an 8-bit PIC16 microcontroller from the PIC® XLP™ 16F family with integrated USB 2.0 full-speed support, 14KB Flash program memory, 1024 bytes RAM, and a maximum CPU clock of 48 MHz, packaged in a 20-pin UQFN (4x4 mm). It targets low-power, USB-enabled embedded designs where board space is at a premium and a wide operating voltage range (2.0V–5.5V typical for the LF variant) is required for battery-powered or USB-bus-powered applications. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, peripherals, and I/O on one silicon die; it executes instructions from on-chip Flash and is the lowest-cost way to add programmable intelligence to a product. The PIC16 architecture uses a Harvard RISC core with a 14-bit instruction word, providing deterministic instruction timing (most instructions execute in one instruction cycle). The PIC16LF1459 specifically extends this base with a USB 2.0 full-speed peripheral, a 48 MHz internal HFINTOSC (required to clock the USB module), 17 general-purpose I/O pins, multiple timers (Timer0, Timer1, Timer2), a 10-bit ADC with up to 9 channels, two comparators, two PWM modules, an EUSART, and an I²C/SPI MSSP. The 'LF' prefix denotes the wide-voltage, low-power variant suitable for both 3.3V and 5V systems as well as battery operation. Key features of the PIC16LF1459T-I/GZ include eXtreme Low Power (XLP) technology with nanoWatt sleep modes that drop quiescent current below 1 µA typical, integrated USB 2.0 full-speed (12 Mbps) with on-chip transceiver and internal pull-up resistor, 14KB self-programmable Flash with 256-byte page size, 1024-byte SRAM data memory, an active clock tuning feature that calibrates the HFINTOSC against a USB SOF packet, and a wide operating voltage of 2.0V to 5.5V. The 20-UQFN (4x4 mm) package is the smallest variant in the PIC16F1459 family and exposes the exposed pad (EP) for thermal dissipation and ground connection. Technically, the device uses Microchip's enhanced mid-range core with a 14-bit instruction set, supports In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD), and offers two PWM modules capable of driving LEDs, motors, or generating analog references. The 10-bit ADC delivers up to 9 channels at 100 ksps, while the comparators can be used for zero-cross detection or low-battery detection. The integrated USB module supports USB 2.0 full-speed device mode with internal pull-up, removing the need for an external USB transceiver. Typical applications include USB HID peripherals such as keyboards, mice, game controllers, and custom HID input devices; USB CDC virtual COM port adapters for legacy serial replacement; low-power IoT sensor nodes with USB firmware-update bootloaders; consumer electronics like toys and remote controls; USB battery chargers and power banks; industrial data loggers with USB download; and educational/development boards (e.g., Microchip Curiosity LPC boards and PIC16F1459-based hobby kits). When designing with this part, note that the 'LF' part-number suffix requires a 48 MHz HFINTOSC when USB is active; if USB is unused, lower-frequency oscillators reduce current draw. The 20-UQFN (4x4 mm) exposed pad must be soldered to the ground plane for thermal performance and signal integrity. Because the USB D+/D- pins are multiplexed, careful pin assignment is required if you also need ADC on more than 9 channels.

PIC16LF1459T-I/SO - 14KB Flash USB MCU, 48MHz | Microchip

The Microchip Technology PIC16LF1459T-I/SO is an 8-bit RISC microcontroller in the PIC16LF family with integrated USB, XLP (eXtreme Low Power) technology, and 14KB of Flash program memory. The device operates at up to 48MHz (200 ns instruction cycle) and packs 1024 bytes of SRAM plus 256 bytes of EEPROM into a 20-pin SOIC (SO) wide-body package, while delivering up to 18 digital I/O pins across the part's peripheral set. An 8-bit PIC microcontroller is a compact, Harvard-architecture CMOS flash MCU built around a reduced instruction set computer (RISC) core. It belongs to the broader taxonomy of microcontroller -> embedded controller -> semiconductor device. PIC16 microcontrollers sit at the entry-level of Microchip's PIC portfolio, pairing deterministic single-cycle instruction execution with a stable, well-supported toolchain (MPLAB X IDE, XC8 compiler, PICkit programmers). The LF prefix denotes the low-voltage (1.8V-3.6V) variant, which is preferred over the F variant for battery-powered designs seeking the lowest sleep current. Key specifications of the PIC16LF1459T-I/SO include 14KB (8192 words) of Flash, 1024 bytes of SRAM, 256 bytes of EEPROM, a 48MHz internal oscillator, an integrated full-speed USB 2.0 device module, a 10-bit ADC with up to 12 channels, two 8-bit timers plus one 16-bit timer, and Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) with SPI and I2C peripherals. The 'T' suffix denotes Tape and Reel packaging; the SO suffix designates the SOIC-20 wide-body package; the -I suffix signifies the industrial temperature grade (-40C to +85C). Architecturally, the PIC16LF1459T-I/SO uses a RISC core that executes most instructions in a single cycle, with a 14-bit instruction word optimized for C code generation. The internal 48MHz oscillator can be tuned for USB applications where 48MHz +/- 0.25% accuracy is required, eliminating external crystals. XLP technology drives the deep-sleep current down to roughly 30 nA, ideal for IoT and sensor node designs where years of battery life are required. Typical applications include USB HID peripherals such as keyboards, mice, and custom input devices; low-power IoT sensor nodes; consumer electronics needing USB connectivity; and battery-powered industrial sensors. The device's USB module supports CDC, HID, vendor-class, and composite device firmware, dramatically shortening the BOM for USB-capable products. Designers should note that the LF part requires VDD between 1.8V and 3.6V and is NOT 5V-tolerant; the regular F variant (PIC16F1459) must be selected for 5V systems. For USB bus-powered designs, an internal 3.3V regulator provides the USB transceiver supply, but external 1 uF decoupling on VUSB is required per the datasheet typical application circuit.

Typical applications include USB HID peripherals such as mice, keyboards, and custom input devices, capacitive touch user interfaces (keypads, sliders, proximity sensors), consumer electronics remote controls, low-power sensor nodes, and industrial control modules with USB diagnostics. The combination of integrated USB and low-power operation removes the need for external regulators and transceivers. Design consideration: when designing USB applications, ensure the D+/D- traces are 90-ohm differential and the VBUS pin sees 5V from the host; the internal 3.3V regulator powers the USB transceiver. For capacitive touch, route the sense traces to minimize parasitic capacitance and use the mTouch software library.

PIC16LF1507-E/P

PIC16LF1507-E/P - 8-Bit MCU, 3.5KB Flash, 20MHz | Microchip

The Microchip Technology PIC16LF1507-E/P is an 8-bit Flash microcontroller from the PIC16 family, featuring a 20MHz CPU, 3.5KB (2K x 14) of Flash program memory, and 128 bytes of RAM, housed in a 20-pin PDIP (DIP-20) through-hole package. The "LF" prefix indicates the low-power XLP variant optimized for battery-friendly operation with extended sleep current performance below typical nanoampere ranges. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals such as timers, ADCs, and communication interfaces on one die. Within the broader taxonomy, an MCU belongs to microcontrollers -> integrated circuits -> semiconductors, and the PIC16 family specifically targets cost-sensitive, low-power embedded designs where deterministic 8-bit processing is sufficient. XLP (eXtreme Low Power) technology from Microchip extends battery life by combining deep-sleep modes with fast wake-up times. Key features include 18 digital I/O pins, a 10-bit ADC with up to 12 input channels, four standalone PWM outputs, a Complementary Waveform Generator (CWG), a Numerically Controlled Oscillator (NCO), two Configurable Logic Cells (CLC), and an integrated temperature indicator. The enhanced mid-range core provides 49 instructions, 16 stack levels, and self read/write Flash capability. Internal oscillators up to 16MHz eliminate the need for external crystals in many designs. The device operates from 1.8V to 3.6V supply, making it ideal for 2xAA / coin-cell applications, and supports 25mA source/sink per I/O for direct LED drive. The "-E" suffix denotes the extended (-40C to +125C) operating temperature grade. Architectural choices favor deterministic interrupt response and small code footprint over raw throughput, which is why PIC16 MCUs remain popular in appliance, sensor, and lighting control designs. Typical applications include battery-powered IoT sensor nodes, LED lighting controllers, consumer appliance interfaces, low-cost motor control (small DC fans, solenoids), and educational/development boards. The combination of low cost, simple toolchain (MPLAB X + XC8), and stable legacy footprint supports long-life industrial designs. When designing with this MCU, ensure decoupling capacitors (100nF plus 10uF bulk) are placed within 5mm of the VDD pin. Use the internal oscillator for prototypes and switch to an external crystal only when USB or strict timing is required. Avoid leaving unused I/O pins floating - configure them as outputs or use the internal weak pull-up.

The Microchip Technology PIC16LF1507-E/SO is an 8-bit RISC microcontroller from the PIC16F150x family featuring an enhanced mid-range core with 49 instructions, 3.5KB (2K x 14 words) of self-read/write Flash program memory, 128 bytes of SRAM data RAM, and 128 bytes of non-volatile EEPROM-like data storage. It operates at clock speeds up to 20MHz, runs from a wide 1.8V to 3.6V supply (the 'LF' variant), and is housed in a 20-pin narrow-body SOIC (SO) package rated for the -40C to +125C industrial/automotive temperature range. What is an 8-bit PIC microcontroller? A PIC (Peripheral Interface Controller) is a Harvard-architecture RISC microcontroller where program and data buses are separated for deterministic single-cycle instruction execution. The PIC16F150x family sits within Microchip's enhanced mid-range portfolio, positioned above baseline PIC10/12/16 cores with a richer peripheral set and below the PIC18 and dsPIC families, targeting cost-sensitive embedded control in appliance, sensor, lighting, and consumer products. Key features include 18 general-purpose I/O pins, a 12-channel 10-bit ADC with voltage reference, four 10-bit PWM modules, a Complementary Waveform Generator (CWG), a Numerically Controlled Oscillator (NCO), two Configurable Logic Cells (CLC), an integrated temperature indicator, and an internal 16MHz oscillator. The device supports both an internal low-power LF oscillator and an external clock source, plus eXtreme Low Power (XLP) technology for battery-aware designs. Typical applications include LED lighting control (constant-current drivers, color-mixing PWM), battery-powered sensor nodes (IoT edge devices), home appliance user interfaces, automotive body controllers, and low-cost motor control loops. The 20-SOIC footprint and 18 I/O pins fit well into compact PCBs where board area is at a premium. When designing with this part, remember that 3.5KB of Flash limits firmware to roughly 2,000-2,500 C instructions, so choose it for state-machine or simple-protocol applications rather than complex stacks. The 'E' suffix denotes the extended temperature grade, and the SO package requires standard 1.27mm pitch SOIC land patterns.

The enhanced mid-range core delivers 49 instructions and 16-level deep hardware stack, with self read/write Flash capability enabling bootloader-free firmware updates. The internal 16MHz oscillator eliminates the need for an external crystal in space-constrained designs. The PIC16LF1507 uses a 14-bit instruction word with single-cycle execution for most instructions, achieving effective throughput close to 5 MIPS at 20MHz FOSC. Typical applications include consumer white goods user interfaces, low-cost IoT sensor nodes, LED lighting controllers, battery chargers, small home appliances, and automotive interior accessories (PIC16LF1507-E grade = -40°C to +125°C). The 20-SSOP footprint is drop-in compatible with the SOIC-20 footprint on many reference designs, easing PCB rework. When designing with this part, allocate a 0.1µF decoupling capacitor within 3mm of VDD, and route the MCLR pull-up (when enabled) directly to VDD. Configure unused I/O as outputs low to minimize quiescent current. The ADC benefits from a 100nF + 10µF analog supply RC network if a separate analog AVSS is used.

PIC16LF1507-I/ML

PIC16LF1507-I/ML - 8-bit MCU, 3.5KB Flash, 20MHz | Microchip

The Microchip Technology PIC16LF1507-I/ML is a low-power 8-bit PIC microcontroller with 3.5KB Flash program memory, 128 bytes RAM, an 8-bit core running at up to 20MHz, and a 20-pin QFN (4x4) package. It belongs to the PIC16LF150x family, which is built around an enhanced mid-range core with 49 instructions and 16-level stack. The LF prefix indicates a wide-voltage variant designed for operation from 1.8V to 3.6V, making it well suited to battery-powered applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and configurable peripherals such as ADCs, timers, PWM channels, and digital I/O on one die. PIC16 series MCUs sit in Microchip's 8-bit PIC architecture hierarchy: PIC16 -> 8-bit PIC -> PIC microcontroller -> microcontroller -> embedded computing -> semiconductor. The 'LF' family specifically targets low-voltage and low-power designs and is favored where coin-cell or Li-ion battery rails of 1.8V-3.6V are present without a boost converter. Key features of the PIC16LF1507 include 3.5KB self-read/write Flash, 128 bytes RAM, four 8-bit timers and one 16-bit timer, a 10-bit ADC with up to 12 input channels, two Configurable Logic Cells (CLC), a Numerically Controlled Oscillator (NCO), Complementary Waveform Generator (CWG), and an internal 16MHz oscillator. The integrated temperature indicator and 25mA source/sink capability on I/O make it a strong fit for compact, mixed-signal, low-power products. Architecturally, the device uses a 14-bit instruction word with a single accumulator (W) and a 9-bit program counter; the 16-level hardware stack eliminates the need for software stack management in most routines. The HFINTOSC can be tuned in firmware, and the LFINTOSC provides an ultra-low-power 31kHz source for sleep-mode timing, supporting deep-sleep currents in the microamp range. Typical applications include consumer IoT battery nodes, e-paper price tags, low-cost remote sensors, simple LED lighting controllers, and space-constrained wearables. Designers also use it as a glue controller in mixed-signal boards where a small 8-bit core is sufficient and BOM cost matters. When designing with this MCU, mind the absolute maximum Vdd of 4.0V - even brief spikes from a USB charger can latch-up the part. A 100nF decoupling cap placed within 3mm of the Vdd pin is mandatory, and the exposed pad (EP) of the QFN package must be soldered to the ground plane for thermal and electrical performance.
