PIC16F1454-E/ML - 8-Bit 48MHz USB MCU 14KB Flash | Microchip

The Microchip Technology PIC16F1454-E/ML is an 8-bit enhanced mid-range microcontroller from the PIC® XLP™ 16F family, integrating a full-speed USB 2.0 transceiver with clock-recovery from the USB host, 14KB (8K x 14) of self-read/write Flash program memory, and 1KB of SRAM in a 16-pin QFN (4x4) package. It runs at up to 48MHz from an internal oscillator, supports 12 I/O lines, and offers 128 bytes of non-volatile data EEPROM, making it a compact, low-pin-count solution for USB-capable embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), working memory (RAM), peripherals, and I/O into one device. The PIC16F1454 is a member of the PIC16 enhanced mid-range family, positioned in the 8-bit MCU category and built on Microchip's Harvard RISC architecture with a 14-bit instruction word. Within the broader taxonomy, it belongs to microcontroller -> 8-bit MCU -> embedded controller -> semiconductor. Its XLP™ (eXtreme Low Power) heritage means standby currents in the microamp range, important for USB bus-powered or battery-powered peripherals. Key differentiating features include the integrated USB 2.0 full-speed module with on-chip transceiver and clock-recovery (no external crystal required for USB), a 49-instruction enhanced mid-range core with 16-level hardware stack, a high-endurance Flash (HEF) cell rated for many program/erase cycles, and a MI2C/SPI master-slave module that supports both I²C and SPI on the same peripheral pins. The 16-QFN (4x4) footprint with exposed pad gives a small board area while keeping thermal performance adequate for the device's modest power dissipation. On the architecture side, the PIC16F1454 uses a 2-stage pipeline RISC core with single-cycle instructions (except branches), a 49-instruction set that adds C-friendly constructs to the classic PIC instruction set, and a configurable 32kHz-48MHz internal oscillator with PLL. The on-chip USB module implements the physical layer, NRZI encoding, and bit-stuffing in hardware; the developer supplies only the device-class firmware (HID, CDC, vendor-class, etc.). Typical applications include USB-to-UART bridge dongles, USB HID input devices (keyboards, mice, custom controls), low-cost USB sensor interfaces, USB charging-cable ID circuits, and small 8-bit general-purpose logic-replacement boards. The wide 2.3V-5.5V operating range also supports industrial 24V-bus systems with simple LDO pre-regulation. When designing with this part, ensure the exposed pad of the QFN is soldered to a sufficiently large copper pour for both thermal dissipation and ground return; the USB bus-powered design budget should account for the MCU's typical run current plus the user-load budget defined by the USB 2.0 specification (100mA low-power, 500mA high-power). For firmware development, MPLAB X IDE with the XC8 compiler and the Microchip Libraries for Applications (MLA) USB stack accelerate class-driver bring-up.

The Microchip Technology PIC16F1458-E/P is an 8-bit PIC® XLP™ 16F microcontroller IC running at up to 48MHz, integrating 7KB (4K x 14) of Flash program memory and 512 bytes of RAM, housed in a 20-pin PDIP (0.300 inch, 7.62mm) through-hole package. It delivers 18 I/O pins, integrated USB 2.0 full-speed support, an enhanced mid-range 14-bit instruction set, and XLP (eXtreme Low Power) technology for battery-friendly designs operating across -40°C to +125°C. A microcontroller (MCU) is a single-chip computer containing a CPU core, Flash program memory, RAM, peripherals, and I/O. Within the broader taxonomy, a PIC16F1xxx MCU belongs to Microchip's enhanced mid-range 8-bit PIC family (microcontroller -> 8-bit MCU -> PIC16F -> PIC16F1xxx enhanced mid-range), positioned for low-cost, low-power, USB-capable embedded designs where simplicity and deterministic interrupt response outweigh raw compute. Key features include on-chip USB 2.0 full-speed transceiver and SIE, 7KB self-programmable Flash, 512B SRAM, 256B EEPROM, two 8-bit timers, one 16-bit timer, 10-bit ADC, PWM modules, and ultra-low-power sleep modes. The 48MHz internal oscillator enables USB clock derivation without external crystals in many designs. The PIC16F1458 employs a Harvard RISC architecture with a 14-bit instruction word and a hardware multiplier, achieving predictable execution timing and deterministic interrupts — a hallmark of PIC microcontrollers favored in real-time control loops and USB HID class applications. Typical applications include USB HID peripherals (keyboards, mice, custom input devices), low-power IoT sensor nodes, consumer electronics with USB connectivity, and educational/development boards where breadboard-friendly 0.3 inch DIP packages simplify prototyping. When designing with this device, ensure the VUSB 3.3V LDO output is properly bypassed (typically 220nF) and consider the internal oscillator trimming for USB applications requiring tight clock accuracy. The DIP-20 footprint is ideal for through-hole prototyping but limits miniaturization versus SOIC/SSOP/QFN variants.

PIC16F1458-E/SO

PIC16F1458-E/SO - 7KB Flash 8-bit MCU USB 48MHz SOIC-20 | Microchip

The Microchip Technology PIC16F1458-E/SO is an 8-bit PIC microcontroller in the PIC16F family featuring 7KB Flash program memory, 512 bytes SRAM, and an integrated USB 2.0 full-speed transceiver. Housed in a 20-pin SOIC package with 0.295 inch (7.50 mm) body width, it operates from a wide 2.3V to 5.5V supply and runs instructions at up to 48 MHz via its internal oscillator, delivering roughly 12 MIPS of throughput. The -E suffix denotes the extended industrial temperature range of -40C to +125C. A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory, working RAM, and a configurable set of peripheral blocks. PIC microcontrollers use a Harvard bus architecture with separate program and data paths, plus RISC instruction set optimized for deterministic interrupt response. The PIC16F1458 sits inside Microchip's PIC16F1xxx mid-range line, which adds USB, capacitive touch sensing (mTouch) and improved peripherals on top of the classic mid-range core. In the system hierarchy it is a sub-category of microcontroller -> embedded controller -> semiconductor IC, optimized for cost-sensitive USB-enabled designs. The part's headline features include 7KB self-programmable Flash, 256 bytes EEPROM, 18 general-purpose I/O pins, a 10-bit ADC with up to 9 channels, multiple PWM/Capture/Compare modules, and a hardware USB 2.0 full-speed transceiver that removes the need for an external PHY or precision 48 MHz crystal. Programmable under Microchip's MPLAB X IDE with the XC8 compiler, it supports in-circuit serial programming (ICSP) and low-power XLP sleep modes drawing under 1 uA. Architecturally the device is built around the enhanced mid-range 14-bit instruction core with a two-stage pipeline and 8-level hardware stack, paired with a clock management block that can derive 48 MHz directly from the internal 16 MHz HFINTOSC via a 3x PLL. This eliminates an external high-frequency crystal for USB and simplifies BOM, while still supporting an external crystal oscillator for applications requiring clock accuracy beyond the internal oscillator's +/- 2% tolerance. Typical applications include USB HID peripherals such as keyboards, mice and game controllers, USB-to-UART bridges, CDC virtual COM ports, low-cost human-interface dongles, capacitive touch buttons (mTouch), and small sensor hubs. The combination of on-chip USB, internal 48 MHz clock and tiny SOIC-20 footprint makes it a frequent choice when board area and BOM cost matter more than processing headroom. When designing with this part, route the USB D+/D- pair as a 90-ohm differential with length matching, place the VBUS sense resistor near the connector, and provide at least 200 nF near the MCU's VDD/VCORE pins. Verify that downstream tools (MCC, USB stack examples) match the latest MPLAB X version for full register compatibility. This page consolidates distributor pricing, drop-in alternatives and practical design notes that go beyond what the standalone datasheet provides.

PIC16F1458-I/P

PIC16F1458-I/P - 8-Bit USB MCU, 7KB Flash, 20-PDIP | Microchip

The Microchip Technology PIC16F1458-I/P is an 8-bit PIC microcontroller from the PIC® XLP™ 16F family, featuring 7KB (4K x 14) of Flash program memory and a 20-pin PDIP through-hole package. The device runs at up to 48 MHz across a 2.4V to 5.5V supply range, integrates a full-speed USB 2.0 transceiver with on-chip USB controller, and supports eXtreme Low Power (XLP) sleep modes for battery-driven designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, non-volatile data EEPROM, and programmable peripherals. PIC microcontrollers use a modified Harvard RISC architecture with a 14-bit instruction word and a separate data bus; they sit at the bottom tier of the embedded computing hierarchy (MCU -> 8-bit microcontroller -> embedded processor) and are deployed wherever deterministic control of simple peripherals (buttons, LEDs, sensors, USB) is needed. The 8-bit core remains popular because it costs less per IO than 32-bit Cortex-M parts and consumes far less active current. Key features of the PIC16F1458 include 7KB Flash, 512 bytes RAM, 256 bytes EEPROM, a 48 MHz internal oscillator with 4x PLL producing the 48 MHz USB clock, a 10-bit ADC up to 100 ksps, two comparators, PWM, I2C/SPI/EUSART, and the integrated USB 2.0 full-speed transceiver. It also adds a 5-bit DAC for USB termination, an on-chip voltage regulator (3.3V) that powers the internal USB transceiver from a 5V bus, and the XLP nanower sleep current rating. USB integration is the defining architectural feature. The 48 MHz system clock is generated from the 16 MHz HFINTOSC and the 3x PLL, which the USB SIE requires. The transceiver includes internal pull-up resistors and 1.5 kΩ pull-up is configurable in firmware, so no external USB pull-up is required. Because the device can self-power the transceiver from VBUS (5V) and present itself as either a bus-powered HID, CDC, or custom endpoint, the BOM for a small USB peripheral shrinks to a connector, two bypass caps, and the MCU. Typical applications include USB HID peripherals (keyboards, mice, custom input devices), USB-to-UART bridges, USB MIDI controllers, low-cost data loggers, sensor-to-USB adapters, battery-powered instruments, and industrial control nodes. The 20-pin PDIP package is breadboard-friendly and well suited to prototyping, hobbyist designs, and low-volume through-hole assemblies where socketed replacement is desirable. When designing with this part, ensure VBUS is connected to pin 14 so the internal USB 3.3V regulator can bias the transceiver, and add 0.1 uF ceramic bypass on VDD and VUSB. The 48 MHz system clock requires PLL configuration after every Fosc startup and is required for any USB transaction. Do not exceed 5.5V on VDD or apply VBUS before VDD. This page synthesizes distributor pricing for 20-PDIP stock, same-package PIC16F family drop-in alternatives, and practical design notes not aggregated on any single datasheet page.
