NXP Semiconductors S9S08LG32J0VLK

Overview

S9S08LG32J0VLK 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 S9S08LG32J0VLK datasheet, S9S08LG32J0VLK pinout, S9S08LG32J0VLK application, or S9S08LG32J0VLK equivalent, key selection criteria include its 80-pin LQFP package, stop3 mode wakeup time (100 µs), I²C 100 kbps support, internal clock source (ICS) with ±2% deviation over voltage/temperature, and LCD charge pump enabling direct glass drive without external components.

Technical Context

The S9S08LG32J0VLK implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with trimmable internal reference (0.2% resolution), enabling bus frequencies from 1 MHz to 20 MHz without external crystal dependency.

Power management includes two low-power stop modes (stop2, stop3), peripheral clock gating, and a low-power on-chip crystal oscillator (XOSC) for RTC and LCD operation during sleep. The ADC runs in stop3 mode and supports automatic compare, bandgap reference, and wake-up capability - critical for battery-powered sensing applications.

FAQ

What is the maximum operating frequency of the S9S08LG32J0VLK CPU core?

The S9S08LG32J0VLK CPU core operates at up to 40 MHz when supplied at 5.5 V within the –40 °C to 85 °C temperature range, and maintains functional operation up to 20 MHz bus frequency across the full –40 °C to 105 °C range using the internal clock source (ICS) with FLL. This ensures deterministic timing for real-time display updates and sensor sampling in automotive environments.

Does the S9S08LG32J0VLK support LCD operation during low-power modes?

Yes, the S9S08LG32J0VLK supports LCD operation in stop3 mode using its low-power on-chip crystal oscillator (XOSC) as clock source. This allows continuous segment driving and real-time clock functionality while consuming minimal current - a key capability confirmed in the Rev. 9 datasheet Section "Power-Saving Modes" and Figure 14 (Typical Stop3 IDD).

What debug interface does the S9S08LG32J0VLK provide?

The S9S08LG32J0VLK provides a single-wire background debug (BKGD) interface via the PTC5 pin, supporting breakpoint setting, on-chip ICE emulation, and three comparator-based trigger modes. This eliminates the need for multi-pin JTAG headers, simplifying PCB layout and reducing debug connector cost - as documented in the "Development Support" section of the MC9S08LG32 Rev. 9 datasheet.

Can the S9S08LG32J0VLK's ADC operate while the MCU is in stop3 mode?

Yes, the S9S08LG32J0VLK's 12-bit ADC can operate fully in stop3 mode, including automatic compare, temperature sensor reading, and wake-up on conversion completion. This capability is explicitly stated in the "Peripherals" section of the Rev. 9 datasheet and enables ultra-low-power sensor monitoring without CPU intervention.

What is the pin-compatible package option for the S9S08LG32J0VLK?

The S9S08LG32J0VLK is specified exclusively in the 80-pin LQFP package (Case 917A, 14 mm × 14 mm) per ordering information in the MC9S08LG32 Rev. 9 datasheet Table 23. No pin-compatible 64-pin or 48-pin variants exist for this exact part number - those pin counts correspond to different device numbers (e.g., MC9S08LG32xxxVLH for 64-pin).
