Orientation is unambiguous under a stereo microscope at 10×. ## Core specs for the BOM line This is an 8-bit S08 core running at 20 MHz, with 4 KB of on-chip Flash program memory and 256 bytes of RAM. On-chip peripherals include a 4-channel 10-bit ADC, plus LVD, POR, PWM, and WDT blocks. Connectivity covers I²C, SCI (UART), and SPI — enough to talk to a temperature sensor, a small display, or a serial EEPROM without external glue logic. The internal oscillator means no external crystal is needed for most applications. A sensor node in an outdoor enclosure or a motor-drive auxiliary board that sees 70 °C internally stays within the operating envelope without derating the core speed. The 4 I/O pins are the limiting factor for system expansion. With the ADC and serial peripherals sharing these pins, a design that needs more than one external interrupt or two dedicated serial buses will run out of pins quickly. This part fits best where the BOM calls for a single sensor reading and a UART link back to a host controller. Sourced through independent distribution channels.","metaTitle":"NXP MC9S08QG4CDNE S08 MCU, 8-bit, 20 MHz, 4KB Flash, 8-SOIC","metaDescription":"NXP MC9S08QG4CDNE 8-bit MCU, S08 core at 20 MHz, 4KB Flash, 256B RAM, 4-ch 10-bit ADC, I²C/SCI/SPI, -40 to 85°C, 8-SOIC.
