The internal oscillator saves the external crystal or resonator, reducing BOM count and board area. ## On-chip peripherals — ADC, PWM, LIN, and supervisor blocks An 8-channel, 10-bit ADC reads analog inputs like temperature sensors or potentiometers directly, without an external converter. The PWM module drives simple motor or LED dimming loads, while the LINbus and SCI interfaces handle serial communication in automotive or industrial sensor networks. Built-in Low-Voltage Detect (LVD) and Power-On Reset (POR) supervise the supply — the MCU resets cleanly on brownout without an external supervisor IC. 24 general-purpose I/O pins are available for keypad scanning, display segments, or relay control. ## Industrial temperature grade and active lifecycle The 28-SOIC wide-body package (7.50 mm width) is a standard surface-mount footprint with good thermal dissipation for moderate loads.","metaTitle":"NXP MC9S08SE4CWL S08 MCU, 20 MHz, 4 KB Flash, 28-SOIC","metaDescription":"NXP MC9S08SE4CWL 8-bit MCU, S08 core at 20 MHz, 4 KB Flash, 256 B RAM, 24 I/O, 8-ch 10-bit ADC, LIN/SCI, -40 to 85°C, 28-SOIC.","metaKeywords":null},"attributes":{"series":"S08","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"20MHz","Series":"S08","Package":"Bulk","RAM Size":"256 x 8","Core Size":"8-Bit","Peripherals":"LVD, POR, PWM","Connectivity":"LINbus, SCI","Mounting Type":"Surface Mount","Number of I/O":"24","Core Processor":"S08","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"4KB (4K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-SOIC","Voltage - Supply (Vcc/Vdd)":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.93","stockQuantity":0,"priceTiers":[{"qty":156,"price":"$1.93000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/39d48624dca99d79d9530663de9d8cc6.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/MC9S08SE4CWL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/MC9S08SE4CWL when reusing this data.
