Communication interfaces include I²C, SPI, and UART/USART, plus LINbus for automotive body networks. On-chip peripherals include a low-voltage detect (LVD) for brownout protection, power-on reset (POR), a PWM module for motor or LED dimming, and a watchdog timer (WDT) for system supervision. The external oscillator input lets you choose the clock source — a crystal, resonator, or external clock — to match the timing accuracy your application needs. ## 20-TSSOP package and board-fit note Housed in a 20-lead TSSOP with a 4.40mm body width and 0.65mm pin pitch, this MCU fits a small PCB footprint. The surface-mount package is suited for reflow assembly; the 0.65mm pitch is manageable on a two-layer board for most designs.","metaTitle":"NXP MC9S08PB8MTJ S08 MCU, 8KB Flash, 20MHz, 20-TSSOP","metaDescription":"NXP MC9S08PB8MTJ 8-bit MCU from S08 family, 20MHz core, 8KB Flash, 1K RAM, 12-ch 12-bit ADC, 20-TSSOP, -40 to +125°C.
