Product details
Overview
MC908QC16CDZER from NXP (formerly Freescale) is an 8-bit HC08-core microcontroller with 16 KB flash, 512 B RAM, 10-bit ADC (up to 10 channels), enhanced SCI supporting LIN 2.0/J2602, and periodic wake-up module - designed as a LIN slave for automotive body electronics including door modules and seat controls.
For engineers reviewing the MC908QC16CDZER datasheet, MC908QC16CDZER pinout, MC908QC16CDZER application, or MC908QC16CDZER equivalent, key selection criteria include LIN-compliant ESCI timing accuracy (<0.4% oscillator error), 16-pin SOIC package with –40°C to +85°C operation, in-circuit flash reprogrammability, and integrated 32 kHz low-power wake-up oscillator.
Technical Context
The MC908QC16CDZER implements the HC08 CPU core with 16 MHz max bus frequency, fully trimmable internal oscillator (1/2/3.2 MHz nominal), and ESCI hardware optimized for LIN 2.0 frame synchronization and break symbol detection. It supports full-duplex UART communication up to 115 kbps with programmable 8-/9-bit character length and separate TX/RX enable control.
Its peripheral set includes four-channel 16-bit timer plus two-channel 8-bit timer, COP watchdog, LVI reset, POR, KBI, and a dedicated 32 kHz periodic wake-up oscillator accessible in all power modes - enabling deterministic low-power exit without external wake signals.
