A 7-channel 10-bit ADC is integrated, and the oscillator is internal, saving a crystal on the BOM. ## NRND status — plan the transition This means STMicroelectronics is phasing out the part; new production designs should not start with this order code. Existing BOM lines can still be filled through independent distribution while stock lasts, but a replacement plan is advisable. ## 20-TSSOP footprint and supply rails The MCU comes in a 20-TSSOP package (4.40 mm width), surface-mount only.","metaTitle":"ST STM8AF6223PCAX 8-bit MCU, 16 MHz, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AF6223PCAX 8-bit MCU, 16 MHz core, 8 KB Flash, AEC-Q100 automotive grade, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tape & Reel (TR)","RAM Size":"1K x 8","Core Size":"8-Bit","EEPROM Size":"640 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"STM8A","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Not For New Designs","Data Converters":"A/D 7x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2590","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bf7b21f4a1a887507e01c07ab726cf0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6223PCAX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6223PCAX obsolete or NRND?","answer":"It is not fully obsolete, but STMicroelectronics is phasing it out.
