For sustainment of current designs, independent distribution channels can source this part against an RFQ. ## Supply voltage flexibility and internal oscillator An internal oscillator is included, reducing external component count, though an external clock can be used when tighter timing accuracy is required. ## 41 I/O lines with brown-out and watchdog supervision With 41 I/O lines, the STM8AL31E88TCX provides ample GPIO for monitoring switches, driving LEDs, and interfacing with parallel peripherals. On-chip brown-out detection and reset, POR, and a watchdog timer (WDT) improve system robustness in noisy automotive environments without external supervisory ICs.","metaTitle":"STM8AL31E88TCX 8-bit MCU, 16 MHz, 64 KB Flash, AEC-Q100","metaDescription":"STMicroelectronics STM8AL31E88TCX 8-bit MCU, 16 MHz core, 64 KB Flash, 4K x 8 RAM, 2K x 8 EEPROM, AEC-Q100 qualified, -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":"Tube","RAM Size":"4K x 8","Core Size":"8-Bit","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"41","Core Processor":"STM8","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 25x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7369","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0b1f5678cea90b5e6c2296890ade9863.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AL31E88TCX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AL31E88TCX obsolete?","answer":"It is not yet fully obsolete, but ST has signaled it will eventually be phased out.
