Product details
Overview
S9S08DN16F2CLF from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip Flash, 2 KB RAM, and 2 KB EEPROM, operating at up to 40 MHz CPU / 20 MHz bus frequency. It integrates ADC, SPI, I²C, SCI (LIN/J2602-capable), TPM, RTC, and analog comparators, targeting embedded control in automotive body electronics and industrial sensor nodes.
For engineers reviewing the S9S08DN16F2CLF datasheet, S9S08DN16F2CLF pinout, S9S08DN16F2CLF application, or S9S08DN16F2CLF equivalent, key selection criteria include Flash size, LIN-compliant SCI support, real-time counter with crystal-based timekeeping, low-voltage detection with interrupt/reset options, and single-wire background debug capability.
Technical Context
The S9S08DN16F2CLF implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and a 3-stage pipeline for deterministic execution. Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based clock synthesis with factory-trimmed internal reference and ±1.5% FLL accuracy over temperature.
On-chip peripherals include a 12-bit, 16-channel ADC with 2.5 µs conversion time and integrated temperature sensor, two analog comparators with bandgap reference option, and dual TPM modules (6-channel + 2-channel) supporting input capture, output compare, and edge-aligned PWM - all functional in wait mode and selectively retained in Stop2/Stop3.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08DN32F2CLF | 32 KB Flash, same package/peripherals; higher memory headroom for bootloader + application partitioning | Preferred where field-upgradable firmware or larger RTOS footprint is required | Select when >16 KB Flash is needed without changing PCB layout or peripheral usage |

FAQ
What is the maximum operating frequency of the S9S08DN16F2CLF CPU and bus?
The S9S08DN16F2CLF features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding maximum bus frequency of 20 MHz. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, and is validated across the full industrial temperature range (–40°C to +105°C) and supply voltage (2.7–5.5 V). The S9S08DN16F2CLF datasheet specifies these values in Section 8.1.1 and Appendix A.
Does the S9S08DN16F2CLF support LIN 2.0 communication natively?
Yes, the S9S08DN16F2CLF includes one Serial Communications Interface (SCI1) explicitly designed to meet LIN 2.0 and SAE J2602 protocol requirements. It supports master extended break generation, slave extended break detection, and wakeup on active edge - all implemented in hardware without CPU intervention. This capability is documented in Chapter 13 of the MC9S08DN60 Series Data Sheet, which covers the S9S08DN16F2CLF.
What are the memory resources available on the S9S08DN16F2CLF?
The S9S08DN16F2CLF integrates 16 KB of on-chip Flash memory, 2 KB of RAM, and 2 KB of EEPROM. Flash supports in-application programming and sector-level erase (4-byte or 8-byte); EEPROM allows byte-level writes and is rated for 100,000 write/erase cycles. All memory blocks are accessible across the full operating voltage and temperature range, as confirmed in Section 4.5 of the official datasheet.
Can the S9S08DN16F2CLF operate from an external 32.768 kHz crystal for real-time clock functions?
Yes, the S9S08DN16F2CLF supports external 32.768 kHz crystals via the RTC oscillator circuit on PTD7 (RTCCLK) and PTD6 (RTCOSC). When configured, this enables precision real-time counter operation for calendar, time-of-day, and task scheduling - independent of main system clock. The RTC module retains functionality in Stop2 and Stop3 modes, as detailed in Chapter 14 of the MC9S08DN60 Series Data Sheet.
Is single-wire background debug supported on the S9S08DN16F2CLF?
Yes, the S9S08DN16F2CLF implements a single-wire background debug interface on the BKGD/MS pin, enabling full in-circuit debugging, flash programming, and real-time bus capture without requiring additional debug pins. This interface is compatible with standard BDM tools and is integral to the HCS08 architecture - verified in Chapter 16 and Section 2.2.4 of the official datasheet.
