On-chip peripherals include low-voltage detect (LVD), power-on reset (POR), and a PWM module for dimming LEDs or driving small DC loads. Serial connectivity covers SCI (UART) and SPI, so it can talk to a host controller or a serial EEPROM. The 1.27 mm pitch is friendly to hand-assembly and rework — a standard hot-air station with a fine nozzle can lift and replace this part without lifting pads, provided the board is preheated to 100°C to reduce thermal shock. Pin 1 is clearly marked by a notch on the package body and a dot on the top surface; no orientation ambiguity.","metaTitle":"MC908QB4MDWER HC08 MCU, 8MHz, 4KB Flash, 16-SOIC","metaDescription":"NXP MC908QB4MDWER 8-bit HC08 MCU, 8MHz core, 4KB Flash, 128B RAM, 13 I/O, 10-bit ADC, -40 to +125°C, 16-SOIC.
