Product details
Overview
S9S08LG32J0VLF 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 (2+6 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 S9S08LG32J0VLF datasheet, S9S08LG32J0VLF pinout, S9S08LG32J0VLF application, or S9S08LG32J0VLF equivalent, key selection criteria include its 80-pin LQFP package, stop3 mode wakeup time (100 µs), I²C 100 kbps support, 12-bit ADC conversion time (2.5 µs), and integrated low-power crystal oscillator for RTC/LCD timing.
Technical Context
The S9S08LG32J0VLF implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its clock system combines a precision internal clock source (ICS) with FLL-based frequency synthesis (1–20 MHz bus) and an external crystal oscillator (XOSC) supporting 31.25 kHz–16 MHz crystals.
Power management includes two low-power stop modes (stop2, stop3), peripheral clock gating, and a dedicated low-power on-chip crystal oscillator usable in stop3 to drive RTC and LCD. The device supports full debug via single-wire background interface with three comparators and eight-deep FIFO in the on-chip ICE module.

FAQ
What is the maximum operating frequency of the S9S08LG32J0VLF CPU core?
The S9S08LG32J0VLF CPU core operates at up to 40 MHz when supplied at 5.5 V across the full temperature range (–40 °C to +105 °C). Bus frequency is derived from the internal clock source (ICS) or external oscillator (XOSC), supporting configurable rates from 1 MHz to 20 MHz for system-level timing control.
Does the S9S08LG32J0VLF support debugging while the device is running in low-power modes?
Yes, the S9S08LG32J0VLF supports background debug via its single-wire BKGD interface even during low-power wait and stop2 modes. However, full debug functionality (breakpoints, register access) is suspended in stop3 mode; the device must wake before resuming debug session control.
Can the S9S08LG32J0VLF drive a 4×41 LCD configuration in its 80-pin LQFP package?
Yes, the S9S08LG32J0VLF in the 80-pin LQFP package supports up to 4×41 or 8×37 LCD segment configurations. This capability is confirmed in Table 1 of the MC9S08LG32 Rev. 9 datasheet and enabled by dedicated LCD[44:0] pins and internal charge pump circuitry.
What are the absolute maximum ratings for supply voltage and I/O pin injection current on the S9S08LG32J0VLF?
The S9S08LG32J0VLF has an absolute maximum supply voltage of –0.3 V to +5.8 V (VDD), and single-pin DC injection current limits of ±2 mA (VIN < VSS or VIN > VDD). Total MCU injection current must not exceed ±25 mA, as specified in Table 8 (DC Characteristics) of the datasheet.
Is the S9S08LG32J0VLF qualified for automotive applications?
Yes, the S9S08LG32J0VLF is AEC-Q100 qualified for automotive use. It meets Grade 2 temperature requirements (–40 °C to +105 °C), includes ESD protection (HBM ≥2500 V), and features system safeguards such as COP watchdog, low-voltage detection/reset, and illegal opcode/address detection - all documented in the MC9S08LG32 Rev. 9 datasheet.
