PIC16F1454-E/JQ Descripción general
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals such as timers, ADC, communication interfaces, and I/O ports. The PIC16F1454 belongs to the PIC16 enhanced mid-range core family - an 8-bit RISC architecture with 49 instructions, 16 stack levels, and self read/write Flash capability that simplifies in-application firmware updates.
Key features include 14 KB High-Endurance Flash (HEF), 128 B of non-volatile data storage (EEPROM-like), an internal 48 MHz oscillator that eliminates an external crystal in many designs, USB 2.0 Full-Speed device support, an MI2C/SPI module, a 10-bit ADC, and Microchip's eXtreme Low Power (XLP) technology for battery-friendly sleep currents. The PIC16F1454 operates from 2.3 V to 5.5 V across -40C to +125C.
Architecturally, the enhanced mid-range core executes most instructions in one instruction cycle (4 clock cycles), giving roughly 12 MIPS at 48 MHz. The USB module integrates a 3.3 V internal regulator and clock-recovery circuitry so the part can derive 48 MHz from the USB host's SOF packets without an external crystal on the USB bus.
Typical applications include USB human-interface devices (HID) such as keyboards, mice, and game controllers; USB-to-UART bridges; small sensor nodes; consumer accessories; and low-cost industrial controllers. The exposed-pad UQFN-16 footprint is well suited to space-constrained PCBs where a 4x4 mm BGA-style pad layout is preferred.
When designing with this device, remember that the UQFN-16 exposed pad must be soldered to a sufficient copper pour for thermal dissipation. The internal USB regulator provides 3.3 V from VBUS but the MCU core logic runs from VDD; ensure adequate bulk capacitance on both rails and follow Microchip's USB layout checklist to pass USB compliance.

Aplicaciones típicas
PIC16F1454-E/JQ es adecuado para 6 aplicacións: USB HID Keyboard / Mouse, USB-to-UART Bridge, USB Sensor / Data-Logging Dongle, Consumer LED Controller / Lighting Accessory, USB Bootloader / Programming Dongle, Industrial USB Sensor / Process Module.
USB HID Keyboard / Mouse
The PIC16F1454-E/JQ is ideal for low-cost USB Human Interface Devices such as keyboards, mice, and gamepads. Its integrated USB 2.0 Full-Speed device controller with on-chip clock recovery from the host SOF packets removes the need for an external 48 MHz crystal, reducing BOM cost and PCB area. The 14 KB Flash comfortably holds Microchip's USB stack plus HID report descriptors, and 512 B RAM is sufficient for typical HID report buffers. The 48 MHz internal oscillator gives 12 MIPS for scan matrix handling.
Recomendado
USB-to-UART Bridge
The PIC16F1454-E/JQ implements a USB CDC class bridge that converts USB to a UART serial port. The on-chip USB 2.0 device module with internal 3.3 V regulator directly interfaces with the host, while the integrated EUSART handles the asynchronous serial side. The 48 MHz core speed provides comfortable throughput for high baud rates up to 1 Mbaud. Designers can load Microchip's CDC stack into 14 KB Flash and still have room for application-specific command parsing.
Recomendado
USB Sensor / Data-Logging Dongle
The PIC16F1454-E/JQ fits USB-attached sensor dongles where a small MCU samples an analog or digital sensor and streams data over USB. The 10-bit ADC samples sensor outputs, the MSSP (MI2C/SPI) talks to digital sensors, and the USB device interface streams data to a host application. The exposed-pad UQFN-16 package keeps the PCB footprint at 4x4 mm, ideal for thumb-drive form factors. The XLP low-power features support battery-powered logging between USB sessions.
Recomendado
Consumer LED Controller / Lighting Accessory
The PIC16F1454-E/JQ powers USB-attached LED controllers and decorative lighting accessories where the MCU decodes host commands to drive WS2812-style LED strips via SPI or bit-banged GPIO. The 48 MHz core provides enough bandwidth to refresh long LED chains at 30 Hz or higher. The USB 2.0 Full-Speed module allows host-side configuration apps to update patterns and color palettes without requiring a dedicated driver. The 2.3 V to 5.5 V VDD range suits both 3.3 V and 5 V LED arrangements.
Recomendado
USB Bootloader / Programming Dongle
The PIC16F1454-E/JQ is a strong fit for USB programming dongles that download firmware to external SPI/I2C Flash or EEPROM targets. The self read/write Flash capability combined with USB and MSSP peripherals enables a complete PC-driven programmer. The 14 KB Flash holds both the USB HID bootloader and the target-programmer command set. The exposed-pad UQFN-16 package supports the compact dongle form factor common for field-service tools.
Recomendado
Industrial USB Sensor / Process Module
The PIC16F1454-E/JQ fits industrial USB sensor modules where it reads 4-20 mA loops, thermocouples, or digital sensors and reports values to a host SCADA system over USB CDC. The 10-bit ADC handles basic analog inputs, the MSSP reads digital sensors, and the EUSART can interface to RS-485 transceivers for hybrid fieldbus designs. The -40C to +125C operating range and XLP low-power features suit harsh industrial environments and remote-monitor battery nodes.

Notas de diseño
The PIC16F1454-E/JQ is supplied in a 16-pin UQFN (4x4 mm) with an exposed thermal pad (EP). The EP must be soldered to a PCB copper pour that is connected to ground; this provides both the primary thermal path and a low-inductance ground reference for the USB signals. Estimate: with EP soldered to at least 1 square cm of 1 oz copper on a 4-layer board, theta_JA is approximately 40 C/W, allowing operation up to the 125 C maximum without derating below 25 C ambient for typical USB HID workloads under 50 mA.
USB differential pair routing must follow the 90-ohm differential impedance guideline. Keep the D+/D- traces short, length-matched within 150 mil, and routed over a continuous ground plane. Place the VBUS decoupling capacitor (typically 4.7 uF) within 5 mm of the VBUS pin and add a ferrite bead if the design must survive ESD strikes. Microchip's USB layout checklist in the datasheet provides the reference routing topology.
The PIC16F1454-E/JQ integrates an internal 3.3 V USB transceiver regulator powered from VBUS. The MCU core logic still runs from the user-supplied VDD (2.3 V to 5.5 V). Add a bulk 10 uF plus a 100 nF ceramic bypass on each of VDD and VBUS. Estimated: at 48 MHz active, core current is approximately 6 mA; sleep current with WDT disabled drops below 1 uA thanks to XLP technology - useful for battery-tethered sensor designs.
Do not omit the 10 kohm pull-up on D- for full-speed USB device enumeration - the host will not detect the device without it. When using the internal HFINTOSC, the active clock tuning register value must be loaded from the factory calibration constant stored in Flash location 0xF000; otherwise USB SOF jitter can fail USB compliance. The MCLR pin (RA3) can be disabled by configuration bit, but disabling it removes the only hardware reset path - leave it enabled for in-circuit programming.
Información de cumplimiento
RoHS and lead-free compliant per Microchip product page. The PIC16F1454-E/JQ is not AEC-Q100 qualified; automotive designs should select the PIC16F1454-E/JQVAO automotive-grade variant or the PIC16F145x family AEC-Q100 qualified parts.
