Microchip Technology PIC64GX1000-V/FCVP

Overview

PIC64GX1000-V/FCVP from Microchip Technology is a 64-bit RISC-V microprocessor with four 600 MHz RV64GC application cores (U54), one 600 MHz RV64IMAC monitor core (E51), integrated 2 MB L2 memory subsystem with SECDED, dual CAN 2.0 interfaces, and PCIe Gen 2 x4 root port - designed for Linux-capable embedded compute in industrial gateways and secure edge nodes.

For engineers reviewing the PIC64GX1000-V/FCVP datasheet, PIC64GX1000-V/FCVP pinout, PIC64GX1000-V/FCVP application, or PIC64GX1000-V/FCVP equivalent, this page delivers verified core architecture, DDR4/LPDDR4 controller specs, security features including dual PUF and sNVM, thermal range (-40°C to +100°C), and package-specific I/O voltage requirements for FCVG484.

Technical Context

The PIC64GX1000-V/FCVP implements a cache-coherent multi-core RISC-V cluster with five physically distinct cores: four U54 application cores sharing L2 resources and one E51 monitor core with dedicated 16 KB iCache/8 KB DTIM. All cores feature Physical Memory Protection (PMP) and SECDED ECC on L1 memories.

Its system interconnect uses an AMBA AXI switch with QoS and memory protection, supporting concurrent high-bandwidth peripherals: dual GigE MACs, HDMI 1.4, MIPI CSI-2, USB 2.0 OTG, and a 32-bit DDR4/LPDDR4 controller operating at 1.6 Gbps - all mapped via a unified 36-bit address space with deterministic LIM and scratchpad modes in L2.

FAQ

What is the maximum DDR4 data rate supported by the PIC64GX1000-V/FCVP?

The PIC64GX1000-V/FCVP integrates a DDR4/LPDDR4 memory controller supporting up to 1.6 Gbps per pin. This translates to an effective 32-bit bus bandwidth of 6.4 GB/s. The controller supports DDR4 at 1.6 Gbps with an 8 Gb addressable memory space and includes full SECDED ECC for error correction - confirmed in DS50003724C Section 6.11 and Table 1-2. PIC64GX1000-V/FCVP does not support DDR5 or higher-speed DDR4 profiles beyond 1.6 Gbps.

Does the PIC64GX1000-V/FCVP support PCIe Gen 3 or only Gen 2?

The PIC64GX1000-V/FCVP supports PCIe Gen 2 exclusively, with a single root port configured for x4 lane width. It does not implement Gen 3 signaling or higher. The PCIe subsystem complies with PCI-SIG Gen 2 specifications, including TxPLL electrical compliance testing per DS50003724C Section 7.5. PIC64GX1000-V/FCVP achieves up to 2 GB/s aggregate bandwidth (500 MB/s per direction) - sufficient for NVMe SSDs and FPGA accelerators in edge applications.

How many RISC-V cores does the PIC64GX1000-V/FCVP contain, and what are their roles?

The PIC64GX1000-V/FCVP contains five RISC-V cores: four U54 RV64GC application cores (each 600 MHz, with MMU, PMP, and 32 KB L1 caches) and one E51 RV64IMAC monitor core (600 MHz, with 16 KB iCache/8 KB DTIM and PMP). The U54 cores run Linux or RTOS workloads; the E51 handles bootloaders, bare-metal monitoring, and real-time tasks. This configuration is explicitly defined in DS50003724C Sections 1 and 5.1–5.2. PIC64GX1000-V/FCVP does not support dynamic core disable or asymmetric multiprocessing beyond this fixed allocation.

What security features are implemented in hardware on the PIC64GX1000-V/FCVP?

The PIC64GX1000-V/FCVP implements hardware-based security including dual physically unclonable functions (PUF), 56 KB secure non-volatile memory (sNVM), Athena F5200 TeraFire Crypto Processor (200 MHz), tamper detectors with countermeasures, and digest integrity checks for both sNVM and eNVM. These are documented in DS50003724C Sections 9.1–9.6 and Table 1-1. PIC64GX1000-V/FCVP enforces secure boot via ECDSA signature verification and supports user-defined PUF-protected boot flows - all without external security ICs.

Is the PIC64GX1000-V/FCVP pin-compatible with other PIC64GX variants like PIC64GX1000-V/FCSG325?

No, the PIC64GX1000-V/FCVP (FCVG484 package) is not pin-compatible with PIC64GX1000-V/FCSG325. The FCVG484 has 484 pins, 0.8 mm pitch, and 19 mm × 19 mm footprint, while FCSG325 has 325 pins, 0.5 mm pitch, and 11 mm × 11 mm footprint - with different pin counts, spacing, and I/O bank allocations. DS50003724C Sections 14.1 and 14.2 confirm separate pinout definitions. PIC64GX1000-V/FCVP requires unique PCB layout and power delivery design versus smaller-package variants.
