NXP Semiconductors S9S08LG32J0CLH

Overview

S9S08LG32J0CLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB flash, 1984-byte RAM, and integrated LCD driver supporting up to 8×37 segments. It operates from 2.7 V to 5.5 V across –40 °C to 105 °C, features dual TPM modules (6+2 channels), 12-bit ADC with temperature sensor, and I²C/SPI/SCI interfaces. It targets automotive instrument clusters and industrial panel meters requiring low-power operation and on-chip display control.

For engineers reviewing the S9S08LG32J0CLH datasheet, S9S08LG32J0CLH pinout, S9S08LG32J0CLH application, or S9S08LG32J0CLH equivalent, key selection criteria include its 80-pin LQFP package, stop3 mode wakeup time (100 µs), internal clock source (ICS) with ±2% deviation over voltage/temperature, 12-bit ADC conversion time (2.5 µs), and LCD charge pump support for 3 V glass.

Technical Context

The S9S08LG32J0CLH implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its clock system integrates a frequency-locked-loop (FLL) in the ICS module, enabling bus frequencies from 1 MHz to 20 MHz with internal reference trimming (0.2% resolution).

Power management includes two low-power stop modes (stop2, stop3), peripheral clock gating, and a low-power on-chip crystal oscillator (XOSC) usable in stop modes for RTC and LCD timing. The device supports LIN-compliant SCI with extended break generation/detection and wakeup on active edge.
