Microchip Technology PIC64GX1000-C/FCV

Overview

PIC64GX1000-C/FCV from Microchip Technology is a 64-bit RISC-V microprocessor with four 600 MHz RV64GC application cores and one 600 MHz RV64IMAC monitor core, integrated 2 MB L2 memory subsystem, dual Gigabit Ethernet MACs, PCIe Gen 2 x4 root port, and DDR4/LPDDR4 32-bit memory controller - deployed in industrial edge gateways requiring Linux-capable deterministic real-time compute.

For engineers reviewing the PIC64GX1000-C/FCV datasheet, PIC64GX1000-C/FCV pinout, PIC64GX1000-C/FCV application, or PIC64GX1000-C/FCV equivalent, key selection considerations include FCVG484 package compatibility, 32-bit DDR bus width, PCIe Gen 2 x4 lane count, industrial temperature range (–40 °C to +100 °C), and secure boot with dual PUF support.

Technical Context

The PIC64GX1000-C/FCV implements a cache-coherent five-core RISC-V cluster: four U54 application cores with MMU, PMP, and 32 KB L1 I/D caches, plus one E51 monitor core with 16 KB iCache/ITIM and 8 KB DTIM - all sharing a flexible 2 MB L2 subsystem configurable as cache, Loosely Integrated Memory (LIM), or Coherent Scratchpad Memory. The CPU complex operates at 1.05 V core supply and supports SV39 virtual memory addressing.

Its system interconnect uses an AMBA AXI switch with QoS and memory protection, enabling concurrent high-bandwidth access to DDR4/LPDDR4 (32-bit, 1.6 Gbps), two GigE MACs, USB 2.0 OTG, HDMI 1.4, MIPI CSI-2, and dual CAN 2.0 controllers - all routed through a unified coherent bus matrix with SECDED ECC on all on-chip memories.

FAQ

What is the operating temperature range for PIC64GX1000-C/FCV?

The PIC64GX1000-C/FCV is rated for industrial temperature operation from –40 °C to +100 °C junction temperature. This specification is confirmed in DS50003724C Table 4-1 and applies specifically to the PIC64GX1000-C/FCV variant in the FCVG484 package. It supports deployment in unconditioned enclosures, factory floors, and vehicle under-hood environments where thermal management is constrained.

Does PIC64GX1000-C/FCV support PCIe Gen 3 or higher?

No, the PIC64GX1000-C/FCV implements a PCIe Gen 2 root port with x4 lane configuration, supporting 5 GT/s per lane. DS50003724C Section 7 and Table 1-2 explicitly state "PCIe Gen 2" - no Gen 3 or Gen 4 capability is included. Designers requiring higher bandwidth must use external switches or alternate processors with native Gen 3+ support.

How does the L2 memory subsystem operate in Loosely Integrated Memory (LIM) mode on PIC64GX1000-C/FCV?

In LIM mode, the 2 MB L2 memory subsystem on PIC64GX1000-C/FCV operates as non-cacheable, tightly timed SRAM - providing deterministic sub-100 ns access latency for time-critical tasks like motor control or safety monitoring. This mode bypasses cache tags and coherence logic, ensuring predictable timing unaffected by cache misses or eviction policies - as defined in DS50003724C Sections 5.5 and 5.6.

What boot options are supported by PIC64GX1000-C/FCV?

The PIC64GX1000-C/FCV supports three boot modes: Microchip secure boot (ECDSA-signed image validation), user-defined PUF-protected secure boot (custom key binding), and direct boot from 128 KB embedded non-volatile memory (eNVM). All are detailed in DS50003724C Section 15 and Table 1-2 - no external SPI flash dependency is required for basic operation.

Is PIC64GX1000-C/FCV pin-compatible with PIC64GX1000-V/FCV?

Yes, PIC64GX1000-C/FCV and PIC64GX1000-V/FCV share identical FCVG484 package, pinout, and electrical characteristics - differing only in speed grade and temperature qualification: the 'C' suffix denotes industrial-grade (-40 °C to +100 °C), while 'V' indicates extended commercial (0 °C to +100 °C). Both comply with DS50003724C Table 1-2 and Section 14.2.
