Operating at up to 48 MHz with 16 KB Flash and 2 KB SRAM, it provides essential peripherals including a 10-bit ADC, op-amp\/comparator, DMA, USART, I2C, SPI, and multiple timers. At approximately $0.10 in bulk, it is one of the most affordable 32-bit MCUs available, ideal for cost-sensitive designs.","working_principle":"The CH32V003F4P6 is built around the QingKe RISC-V2A processor core implementing the RV32EC instruction set. The core features a programmable interrupt controller (PFIC) with hardware interrupt stack for fast context switching and 2-level interrupt nesting. Internal bus architecture connects the CPU to Flash, SRAM, and peripheral modules. The clock system supports internal 24 MHz RC (factory-trimmed), internal 128 KHz RC, and external crystal sources. Power management provides Sleep and Standby modes. The DMA controller with 7 channels offloads data transfer from the CPU for TIM, ADC, USART, I2C, and SPI.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>VDD<\/td><td>Power<\/td><td>Digital power supply (2.7-5.5V)<\/td><\/tr>\n<tr><td>2<\/td><td>PB0\/TXD<\/td><td>I\/O<\/td><td>GPIO \/ USART transmit<\/td><\/tr>\n<tr><td>3<\/td><td>PB1\/RXD<\/td><td>I\/O<\/td><td>GPIO \/ USART receive<\/td><\/tr>\n<tr><td>4<\/td><td>PB2<\/td><td>I\/O<\/td><td>General-purpose I\/O<\/td><\/tr>\n<tr><td>5<\/td><td>PB3\/ADC_IN3<\/td><td>I\/O<\/td><td>GPIO \/ ADC channel 3<\/td><\/tr>\n<tr><td>6<\/td><td>PB4<\/td><td>I\/O<\/td><td>General-purpose I\/O<\/td><\/tr>\n<tr><td>7<\/td><td>PB5<\/td><td>I\/O<\/td><td>General-purpose I\/O<\/td><\/tr>\n<tr><td>8<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr>\n<tr><td>9<\/td><td>PB6\/SPI_SCK<\/td><td>I\/O<\/td><td>GPIO \/ SPI clock<\/td><\/tr>\n<tr><td>10<\/td><td>PB7\/SPI_MOSI<\/td><td>I\/O<\/td><td>GPIO \/ SPI MOSI<\/td><\/tr>\n<tr><td>11<\/td><td>PA0\/ADC_IN0<\/td><td>I\/O<\/td><td>GPIO \/ ADC channel 0<\/td><\/tr>\n<tr><td>12<\/td><td>PA1<\/td><td>I\/O<\/td><td>GPIO \/ PWM output<\/td><\/tr>\n<tr><td>13<\/td><td>PA2<\/td><td>I\/O<\/td><td>GPIO \/ Timer capture<\/td><\/tr>\n<tr><td>14<\/td><td>PA3<\/td><td>I\/O<\/td><td>GPIO \/ Timer compare<\/td><\/tr>\n<tr><td>15<\/td><td>RESETN<\/td><td>Input<\/td><td>Reset (active low)<\/td><\/tr>\n<tr><td>16<\/td><td>XTL_OUT<\/td><td>Osc<\/td><td>External crystal output<\/td><\/tr>\n<tr><td>17<\/td><td>XTL_IN<\/td><td>Osc<\/td><td>External crystal input<\/td><\/tr>\n<tr><td>18<\/td><td>SDIO\/NMI<\/td><td>I\/O<\/td><td>Debug interface \/ NMI<\/td><\/tr>\n<tr><td>19<\/td><td>VDDA<\/td><td>Power<\/td><td>Analog power supply<\/td><\/tr>\n<tr><td>20<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>Ultra-low-cost 32-bit replacement for traditional 8-bit MCU designs<\/li>\n<li>Consumer electronics and smart home appliance controllers<\/li>\n<li>Industrial sensor nodes with ADC and DMA capability<\/li>\n<li>USB peripheral controllers and communication bridges<\/li>\n<li>Small motor control applications using complementary PWM<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr>\n<tr><td>GigaDevice<\/td><td>GD32E230F4P6<\/td><td>TSSOP-20<\/td><td>ARM Cortex-M23, more expensive<\/td><\/tr>\n<tr><td>STMicroelectronics<\/td><td>STM32C011F4P6<\/td><td>TSSOP-20<\/td><td>Cortex-M0+, 48MHz, higher cost<\/td><\/tr>\n<tr><td>WCH<\/td><td>CH32V003A4M6<\/td><td>SOP-16<\/td><td>Same core, fewer pins, SOP16 package<\/td><\/tr>\n<tr><td>WCH<\/td><td>CH32V003J4M6<\/td><td>SOP-8<\/td><td>Same core, minimal 8-pin package<\/td><\/tr>\n<tr><td>Puya<\/td><td>PY32F002AW15S<\/td><td>SOP-16<\/td><td>Cortex-M0+, 24MHz, low cost<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/6603","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=6603"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/6603\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=6603"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=6603"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=6603"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=6603"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
