What is PVTM? Or why your Rockchip RK3588 CPU may not reach 2.4 GHz

Rockchip PVTM

While the Rockchip RK3588 processor is advertised as reaching 2.4 GHz, not all RK3588 chips may achieve this frequency. The keyword is PVTM (Process-Voltage-Temperature Monitor), and we’ll try to explain why it does, and why some of the RK3588 processors may only be clocked at about 2.3 GHz, while others will run fine at 2.4 GHz. This all started with Rock 5B SBC debug party, where we noticed our boards did not reach the same frequency. Willy Tarreau noted the “pvtm” value was different between our boards: Willy’s board: (Cortex-A76 cluster 1 @ 2,304 MHz, cluster 2 @ 2,352 MHz)

CNXSoft board (Cortex-A76 cluster 1 @ 2,304 MHz, cluster 2 @ 2,304 MHz) :

Thomas Kaiser (tkaiser) board: (Cortex-A76 cluster 1 @ 2,400 MHz, cluster 2 @ 2,400 MHz)

For reference, CPU 0 to 3 are Cortex-A55 cores, CPU 4-5 are two Cortex-A76 cores (cluster 1), and […]

CANDuino v3 – A Microchip ATmega168PA board with CAN bus, Arduino Nano form factor

CANDuino v3

CANduino v3 is the third revision of MassiveButDynamic’s CAN bus board with Arduino Nano form factor based on Microchip ATmega168PA 8-bit AVR microcontroller, Microchip MCP2515 CAN controller with an SPI interface, and Microchip MCP2551 CAN transceiver suitable for 12V and 24V systems. The CANDuino v3 board is now slightly narrower in order to give access to two rows on each side when installed on a breadboard, comes with a USB Type-C port to reduce the number of cables needed, and the CAN bus function can be deactivated via a jumper in order to use the CANduino as a normal Arduino Nano. CANDuino v3 specifications: MCU – Microchip ATmega168PA 8-bit AVR microcontroller @ up to 16 MHz with 16KB flash, 512 bytes EEPROM, 1 KB SRAM CAN Bus CAN L/H header and CAN bus termination Microchip MCP2515 CAN controller connected to the AVR microcontroller over SPI.

YD-CH32V307VCT6 RISC-V MCU board comes with Ethernet and plenty of I/Os

VCC-GND Studio CH32V307 RISC-V Ethernet board

At the beginning of the year, we wrote about WCH CH32V307 RISC-V microcontroller and a development board with 8 UART ports controlled over Ethernet. I’ve now been informed of a similar, but much more compact by VCC-GND Studio named “YD-CH32V307VCT6”. Besides the 144 MHz RISC-V microcontroller, the board features a 10Mbps Ethernet port, two USB Type-C ports, SPI flash, EEPROM, a microSD card socket, and four rows of 24 pins each for a total of 96 pins exposing all pins out of the LQFP100 package.

can2040 project adds software CAN bus to Raspberry Pi RP2040 microcontroller

Raspberry Pi RP2040 can2040 software CAN Bus

The can2040 project is a software CAN bus implementation for the Raspberry Pi RP2040 microcontroller that leverages programmable I/Os (PIO) to achieve reading and writing CAN 2.0B data frames at rates up to 1Mbit per second. Kevin O’Connor, the developer of the project, further explains the implementation uses only one of the two RP2040 PIO hardware blocks, so it is possible for a single Raspberry Pi RP2040 chip to have two separate CAN bus interfaces. Some processing also happens on one of the Arm Cortex-M0+ cores of the microcontroller with the processing time dependent on the amount of bus traffic, and a fully saturated CAN bus at the fastest supported rate of 1Mbit/s may use up to around 30% of that core when clocked at 125MHz, so that should still leave plenty of room for other tasks that may run on the system. I could not find any information about […]
