NXP MC9S08GW64 Reference Manual and Addendum
Comprehensive reference manual for MC9S08GW64 and MC9S08GW32 8-bit MCUs, including updated ADC16 calibration procedures for improved linearity in differential mode.
Overview
This document consists of the MC9S08GW64 Reference Manual (Rev 3) and an accompanying Addendum (Rev 1) for the MC9S08GW64 and MC9S08GW32 8-bit HCS08 microcontrollers. It provides technical specifications for the CPU core, memory mapping, and power-saving modes. The manual details integrated peripherals including an LCD driver (up to 4x40 or 8x36), dual 16-bit ADCs (ADC16), and an independent real-time clock (iRTC) with tamper detection. The addendum specifically introduces an adjusted calibration procedure for the ADC16V1 module to improve linearity and minimize error spikes near the 1/4, 1/2, and 3/4 points of the full-scale range when operating in differential mode.
Use Cases
- Smart metering and automatic meter reading (AMR)
- Battery-powered portable instrumentation
- Industrial control and monitoring
- Medical monitoring devices with LCD displays
- Tamper-resistant real-time clock applications
