The 32 KB on-chip FLASH (32K x 8) and 768 bytes of RAM (768 x 8) provide enough code and data space for moderate-complexity control applications — think motor commutation loops, sensor fusion, or serial protocol bridges. The 56-PSDIP through-hole package (56-SDIP, 0.600\" body width, 15.24 mm pitch) makes this part a natural fit for prototyping runs, rework-friendly designs, or legacy board spins where a QFP or BGA would complicate the assembly process. The through-hole body also handles repeated thermal cycling better than fine-pitch SMD packages in high-vibration environments. ## Peripheral set and I/O budget for sensor-actuator control 36 general-purpose I/O lines give this MCU enough headroom to interface with a keypad, a small character LCD, and a handful of discrete sensors without an external port expander. The 10-channel, 10-bit ADC captures analog signals from potentiometers, thermistors, or current-sense resistors directly — no external ADC needed for 10-bit resolution applications. On-chip peripherals include Low-Voltage Detect (LVD) for brown-out protection, Power-On Reset (POR) for clean startup, and a PWM module for driving small DC motors, solenoids, or LED dimming. The SCI (UART) and SPI serial interfaces handle communication with external EEPROM, digital potentiometers, or a host controller over a simple two-wire or four-wire bus. For applications requiring tighter timing accuracy, an external clock source can still be fed into the oscillator input. ## Supply range and temperature grade for industrial deployment ROHS3 compliance means the part is fully lead-free and compatible with current RoHS assembly processes — no special handling or exemption paperwork needed for EU-market products. ## Sourcing posture for volume and MRO replenishment The active status also means NXP continues to support this device with datasheets, application notes, and errata documentation.","metaTitle":"NXP MC908MR32VBE HC08 MCU, 8MHz, 32KB FLASH, 56-PSDIP","metaDescription":"NXP MC908MR32VBE 8-bit HC08 MCU, 8MHz core, 32KB FLASH, 768B RAM, 36 I/O, 10x10b ADC, -40°C to 105°C, 56-PSDIP.
