NXP Semiconductors MC9S08SH32VTL

Overview

MC9S08SH32VTL from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB on-chip FLASH, 2 KB RAM, and a 40-MHz CPU core. It integrates ADC (16-channel, 10-bit), dual TPM PWM modules, SCI/LIN, SPI, I²C, RTC, and analog comparators - deployed in automotive body control modules, industrial sensor nodes, and appliance motor controllers.

For engineers reviewing the MC9S08SH32VTL datasheet, MC9S08SH32VTL pinout, MC9S08SH32VTL application, or MC9S08SH32VTL equivalent, key selection criteria include stop3-mode operation with RTC/ADC/ACMP active, ICS clock trimming accuracy (±0.2% at room temperature), and single-wire background debug interface compatibility with standard BDM tools.

Technical Context

The MC9S08SH32VTL implements the S08CPUV3 core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its Internal Clock Source (ICS) uses a frequency-locked loop (FLL) with factory-trimmed internal reference, enabling bus frequencies from 2 MHz to 20 MHz across voltage and temperature.

Peripherals operate under multiple power modes: ADC, ACMP, and RTC remain functional in Stop3 mode using the 1-kHz on-chip oscillator; SCI supports LIN master break generation and wake-up; TPM modules deliver edge- or center-aligned PWM with input capture and output compare on four total channels.

Key Specifications

Pinout & Package

MC9S08SH32VTL is packaged in a 28-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm pitch, JEDEC MO-153 compliant, footprint compatible with SOIC-28 but with reduced height and thermal resistance.

FAQ

What is the maximum operating frequency of the MC9S08SH32VTL CPU core?

The MC9S08SH32VTL features an HCS08 CPU core rated for up to 40 MHz operation. This maximum frequency is achievable when powered within the specified 2.7–5.5 V supply range and operating within the full industrial temperature range (−40°C to +105°C). The actual bus frequency depends on the selected clock source and ICS configuration, with supported bus speeds ranging from 2 MHz to 20 MHz.

Does the MC9S08SH32VTL support LIN communication natively?

Yes, the MC9S08SH32VTL's SCI module supports LIN 2.0 protocol natively. It provides LIN master extended break generation and LIN slave extended break detection, enabling direct connection to LIN transceivers without external protocol translation. This capability is confirmed in the official MC9S08SH32 data sheet Rev. 3, Section 14.1.1, and is implemented in hardware for deterministic timing compliance.

Can the MC9S08SH32VTL operate in ultra-low-power modes with ADC active?

Yes, the MC9S08SH32VTL supports ADC operation in Stop3 mode - its lowest-power stop mode. In Stop3, the 1-kHz internal oscillator remains active, allowing the 10-bit ADC to perform conversions, including use of the internal temperature sensor and bandgap reference. This is documented in Section 9.4.7 of the MC9S08SH32 data sheet Rev. 3 and enables battery-powered sensor applications with sub-μA quiescent current.

What debug interface does the MC9S08SH32VTL use, and is external hardware required?

The MC9S08SH32VTL uses a single-wire background debug (BDM) interface accessible via the BKGD/MS pin. A standard BDM pod (e.g., P&E Multilink or OSJTAG) is required for programming and debugging - no JTAG header or additional pins are needed. This interface supports flash programming, breakpoint setting, and real-time register inspection as described in Chapter 17 of the MC9S08SH32 data sheet.

Is the MC9S08SH32VTL pin-compatible with other devices in the SH-series?

Yes, the MC9S08SH32VTL in the 28-TSSOP package (VTL suffix) shares identical pinout and electrical characteristics with MC9S08SH16VTL and MC9S08SH8VTL. This allows hardware reuse across memory variants - firmware and PCB design can be scaled by selecting the appropriate FLASH size without layout changes, as confirmed in Appendix B of the MC9S08SH32 data sheet Rev. 3.
