Product details
Overview
S9S08AW16AE0CLD from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip FLASH, 1 KB RAM, and a 20 MHz bus frequency. It integrates dual SCI, SPI, I²C, 16-channel 10-bit ADC, two 16-bit TPM modules (2- and 6-channel), KBI, and single-wire background debug interface. It targets cost-sensitive industrial control and sensor interface applications in 48-pin QFN packages.
For engineers reviewing the S9S08AW16AE0CLD datasheet, S9S08AW16AE0CLD pinout, S9S08AW16AE0CLD application, or S9S08AW16AE0CLD equivalent, key selection criteria include its 48-pin QFN footprint, 20 MHz bus speed, integrated real-time interrupt (RTI), low-voltage detect (LVD) with interrupt/reset, and support for Wait + Stop2/Stop3 power-saving modes.
Technical Context
The S9S08AW16AE0CLD implements the HCS08 CPU core with BGND instruction and single-wire BDM interface, enabling in-circuit debugging without dedicated JTAG pins. Its internal clock generator supports multiple modes including FEI, FEE, FBE, and SCM, with NVM-trimmed internal reference for ±2% accuracy across temperature and voltage.
Peripherals are memory-mapped and share a unified 20 MHz bus; the ADC includes automatic compare and temperature sensor input, while both TPM modules support edge-aligned PWM, input capture, and buffered centered PWM (CPWM) on all channels - configurable independently per module.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9RS08KA2 | 8 KB FLASH, 512 B RAM, 20 MHz bus, 16-pin DFN - lacks ADC, SCI, and TPM modules | Targeted at ultra-low-cost, minimal-peripheral applications like simple LED sequencers or button controllers | Select when system requires only basic GPIO and BDM debug, with strict size/cost constraints and no analog or serial needs |

FAQ
What is the maximum bus frequency supported by the S9S08AW16AE0CLD?
The S9S08AW16AE0CLD supports a maximum bus frequency of 20 MHz. This value is derived from its internal clock generator configuration and determines the timing for all peripherals including ADC conversion cycles, SCI baud rates, and TPM counter increments. The S9S08AW16AE0CLD achieves this via FLL-engaged modes (FEI/FEE) using either internal trimming or external crystal sources, and it is validated across the full operating temperature range (−40°C to +85°C).
Does the S9S08AW16AE0CLD include hardware support for PWM generation?
Yes, the S9S08AW16AE0CLD includes two independent 16-bit Timer/PWM (TPM) modules: one with 2 channels and another with 6 channels. Each channel supports edge-aligned PWM, input capture, and output compare. Both modules also support buffered centered PWM (CPWM), enabling symmetrical waveform generation critical for reduced EMI in motor and lighting control. These features are implemented in hardware and require no CPU intervention once configured.
What debug interface does the S9S08AW16AE0CLD use, and what pins are required?
The S9S08AW16AE0CLD uses a single-wire Background Debug Mode (BDM) interface compliant with Freescale's HCS08 BDM specification. Only the BKGD/MS pin is required for bidirectional debug communication, along with VDD, VSS, and RESET for target power and reset control. No additional debug clock or data lines are needed, simplifying PCB layout and reducing connector count compared to JTAG-based solutions.
Can the S9S08AW16AE0CLD operate in low-power modes, and which ones are supported?
Yes, the S9S08AW16AE0CLD supports Wait mode plus two Stop modes: Stop2 and Stop3. In Stop2 mode, current consumption drops to approximately 1.5 µA (typical) with RTC and LVD active; Stop3 disables LVD and reduces current further. All modes retain RAM contents and support wake-up via IRQ, RTI, or LVD events. These modes are fully documented in the S9S08AW16AE0CLD datasheet Chapter 3 and verified across voltage and temperature ranges.
Is the S9S08AW16AE0CLD pin-compatible with other members of the AW-series, such as the S9S08AW32 or S9S08AW60?
No, the S9S08AW16AE0CLD is not pin-compatible with S9S08AW32 or S9S08AW60 in the same package variant. While all three share the 48-pin QFN option (98ASA00466D), the S9S08AW32 and S9S08AW60 have different pin mappings for certain peripherals - notably SCI1 and TPM1 signals - due to larger FLASH/RAM requiring alternate signal routing. Pin compatibility must be verified per device using the respective "Pins and Connections" chapter in each datasheet.
