MPN: PIC24EP256GU814-E/PH ✓ AktifPIC24EP256GU814-E/PH Ringkasan
A 16-bit MCU (microcontroller unit) is a single-chip computer that integrates a CPU, program memory (Flash), data memory (RAM), and peripheral interfaces on one die. Within Microchip's hierarchy it sits in the PIC24E "high-performance" sub-family, which extends the 16-bit dsPIC DSC line with up to 70 MIPS core speed, large RAM and enhanced peripherals. This places it above 8-bit PIC MCUs in computational power while remaining simpler than 32-bit ARM Cortex parts, making it a frequent choice for mid-range industrial, automotive, and motor-control designs.
Key features include 256 KB (85.5 K x 24) self-programmable Flash, 28 KB RAM, four 40 MIPS comparators, four op amps, and four 12-bit ADC modules offering 1.1 Msps conversion, plus dual 10-bit DACs. The 144-TQFP exposes 122 general-purpose I/O pins, four I2C, four SPI, and four UART channels. A 16-bit Parallel Master Port and PMP-style graphics interface enable direct connection to TFT displays, while the dual CAN 2.0 controllers suit automotive and industrial networks.
The part is AEC-Q100 qualified for automotive environments and operates across -40C to +125C with a 3.0 V to 3.6 V supply. According to the Microchip datasheet DS70621C (cited by distributor listings), the device supports high-speed PWM at 184 ps resolution, making it ideal for digital power conversion and multi-axis motor control. The dedicated USB 2.0 full-speed transceiver eliminates an external PHY, lowering BOM cost for HID and CDC-class peripherals.
Typical applications include industrial automation controllers, CAN-based sensor nodes, USB-connected HIDs (keyboards, custom peripherals), BLDC/PMSM motor drives, and automotive body/ECU modules. The -E/PH temperature grade and AEC-Q100 qualification are specifically designed for under-hood and chassis ECUs operating at extended temperatures.
Designers should allocate decoupling on every AVDX/VDD pin and follow the recommended ground plane strategy in Microchip AN1418 for switching noise immunity. Note that the device operates from an internal PLL at full 60 MIPS - oscillator accuracy of 0.25% or better is recommended for USB full-speed compliance.

Catatan Desain
Decoupling: Place a 0.1 uF ceramic capacitor within 5 mm of every VDD/VDDCORE pin, plus a bulk 10 uF tantalum or ceramic near the package. The PIC24EP256GU814-E/PH core draws up to 100 mA at 60 MIPS (estimated from datasheet typical characteristics). An additional 4.7 uF is recommended on AVDD with a ferrite bead separating digital and analog supplies to prevent ADC noise coupling.
USB PCB layout: Maintain 90-ohm differential impedance on the D+/D- traces, route them over a continuous ground plane, and keep total length under 50 mm. Place the VBUS voltage-divider resistors within 5 mm of the VBUS pin. Per USB 2.0 spec, the D+/D- traces must be matched within 150 ps to avoid signal-integrity violations.
Crystal selection: Use a fundamental-mode crystal between 4 MHz and 10 MHz with effective load capacitance matched to the on-chip oscillator load (typically 15-20 pF). For USB full-speed operation, the accuracy must be within +/-0.25% over the operating temperature range; otherwise enumeration will fail on strict USB hosts.
Power dissipation in the 144-TQFP package is bounded by thermal resistance theta_JA of approximately 45 C/W (4-layer PCB with thermal vias, estimated). At 60 MIPS and 3.3 V, the core dissipates roughly 200 mW (estimated from datasheet IDD figure), resulting in a junction-to-ambient rise of about 9 C, well within the 125 C maximum.
MCLR pin must not be left floating; tie it to VDD through a 10 kohm pull-up with a 100 nF to ground for in-circuit programming. Configuration bits must set the FNOSC, POSCMD, and IESO bits correctly or the device will fail to start. Finally, the JTAG pins (PGECx/PGEDx) are multiplexed with ANx inputs - assign them carefully if using analog functions on those pins.
