PIC32MX564F064LT-V/BG Présentation

The Microchip Technology PIC32MX564F064LT-V/BG is a 32-bit MIPS32 M4K PIC microcontroller operating at up to 80 MHz with 64 KB Flash and 32 KB SRAM, housed in a 121-pin TFBGA (10x10 mm) package for space-constrained high-IO embedded designs. It integrates USB-OTG, CAN, 10-bit ADC, and DMA on a single die, enabling compact communication gateways and industrial control nodes.

A PIC microcontroller (Programmable Integrated Circuit MCU) is a microcontroller built around a Harvard-architecture CPU with on-chip Flash, RAM, and a rich peripheral set. Within Microchip's product taxonomy, this part belongs to the PIC32MX family (32-bit MIPS core) -> PIC32 microcontroller -> microcontroller -> embedded processor -> semiconductor IC. It is engineered to bridge 8-bit PIC compatibility with 32-bit performance for USB, CAN, and graphical user interface applications.

Key features include 64 KB (64K x 8) Flash program memory, 32 KB SRAM, 8 DMA channels, a 10-bit ADC with multiple channels, USB-OTG full-speed on-chip transceiver, CAN 2.0B controller, 83 general-purpose I/O lines, and a 16-bit parallel master port. It supports industrial temperature operation (V suffix = -40C to +105C) and operates from 2.3V to 3.6V supply.

The MIPS32 M4K core delivers 1.56 DMIPS/MHz (Dhrystone 2.1) with single-cycle hardware multiply/divide, while the on-chip DMA controller offloads peripheral data movement to improve throughput for USB, CAN, and ADC streams. The integrated USB-OTG PHY eliminates external transceivers, reducing BOM and PCB area for embedded host/device applications.

Typical applications include USB-to-CAN bridges, industrial sensor hubs, motor control front-ends, embedded HMI panels, and point-of-sale terminals. Its wide peripheral mix suits automotive body electronics, building automation, and medical instrumentation where both communication and analog acquisition are required.

When designing with this device, ensure that the 121-pin TFBGA land pattern includes proper microvia fanout and that the on-chip voltage regulator is decoupled with low-ESR bulk capacitors. Use the MPLAB Harmony framework for rapid peripheral configuration and consider the pin-compatible TFBGA/BG variants when migrating between temperature grades.

This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet. Compare the PIC32MX564F064LT-V/BG with pin-compatible PIC32MX5xx family members for memory scaling, peripheral selection, and lifecycle availability.

Principaux différenciateurs

Wider temperature range than I-grade variants (vs PIC32MX564F064L-I/BG)
Better peripheral density than larger-Flash siblings (vs PIC32MX460F512L-80V/BG)
Modernized USB-OTG over legacy MX3xx (vs PIC32MX360F512L-80V/BG)
Smaller Flash footprint option for cost-sensitive designs (vs PIC32MX564F128L-I/BG)

Notes de conception

The 121-TFBGA package at 10x10 mm with 0.8 mm ball pitch requires PCB microvia (laser-drilled, stacked) technology for inner-row ball escape routing. According to Microchip packaging specification 00000052D, design rules require minimum 0.15 mm via pad and 0.1 mm drill. Place a continuous ground plane on layer 2 beneath the BGA to reduce reference plane impedance discontinuities and improve signal integrity for high-speed USB signals.

PIC32MX564F064LT-V/BG operates from 2.3V to 3.6V with internal voltage regulator requiring 10uF bulk decoupling on VDDCORE plus 0.1uF ceramic on each VDD pin. Per Microchip datasheet DS60001156G, place decoupling capacitors within 5 mm of each supply pin. The internal LDO dissipates VIN-VOUT multiplied by quiescent current; at 80 MHz with all peripherals active, expect ~30 mA core current and ~15 mA I/O current.

Do not exceed 3.6V on any digital I/O pin, even temporarily, as the PIC32MX5xx family has no 5V tolerance on most pins. The USB D+/D- pins require series 27-ohm resistors and the VBUS pin must be connected through a voltage divider for OTG session detection. Configuration bits must be set correctly for the PLL and oscillator mode; failure to configure FNOSC, POSCMD, and PLLIDIV properly results in the device remaining in reset.

USB-OTG Full-Speed (12 Mbit/s) requires 90-ohm differential impedance on D+/D- traces with matched length within 150 mil. CAN signals (CANTX/CANRX) need 120-ohm termination at the bus ends and short stubs to the transceiver. Keep analog ADC traces away from switching signals; use a ground guard ring around sensitive analog inputs to reduce digital switching noise coupling.
