WCH CH32V006 RISC-V microcontroller adds more I/Os, memory, and storage compared to CH32V003
-
WCH CH32V006 RISC-V microcontroller is an upgrade to the 10-cent CH32V003 microcontroller with more I/Os, up to four times the memory, storage, a wider supply voltage range, the addition of a TouchKey interface, as well as a new 32-bit V2C RISC-V core instead of the V2A core found in the CH32V003. More specifically that means we went from the CH32V003 with 2KB SRAM and 8KB flash, up to 8KB SRAM and 62KB for the CH32V006, and 6KB SRAM and 32KB flash for the CH32V005, a smaller sibling of the new RISC-V microcontroller. WCH CH32V005 & CH32V006 specifications (with highlights in bold to show differences against CH32V003): CPU – 32-bit “RISC-V2C” core up to 48 MHz Memory – 6KB SRAM (CH32V005) or 8KB SRAM (CH32V006) Storage – 32KB flash (CH32V005) or 62KB flash (CH32V006) Peripherals Up to 31x GPIO with interrupt support (CH32V003 had up to 18x GPIO) 2x USART interfaces [...]
