NXP Semiconductors MC9S08DN16CLC

Overview

MC9S08DN16CLC 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 (12-bit, 16-channel), dual analog comparators, SCI (LIN 2.0/J2602 compliant), SPI, I²C, two TPM modules, RTC, and real-time interrupt capability - deployed in automotive body control modules and industrial sensor nodes.

For engineers reviewing the MC9S08DN16CLC datasheet, MC9S08DN16CLC pinout, MC9S08DN16CLC application, or MC9S08DN16CLC equivalent, key selection criteria include Flash size (16 KB), EEPROM endurance (100K erase/write cycles), 53 GPIO with configurable slew rate and pull devices, and support for Stop3/Stop2 low-power modes with RTC wake-up.

Technical Context

The MC9S08DN16CLC implements the S08CPUV3 core with HC08 instruction set extension (BGND), supporting up to 32 interrupt/reset sources and single-wire background debug. 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.

Peripherals include a 12-bit ADC with 2.5 μs conversion time and internal temperature sensor, two analog comparators with bandgap reference option, and SCI1 with LIN 2.0 master/slave break generation/detection - all functional in Run, Wait, and Stop3 modes with selective peripheral clock gating.

FAQ

What is the maximum operating frequency of the MC9S08DN16CLC CPU and bus?

The MC9S08DN16CLC features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding maximum bus clock 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 +85°C) and supply voltage (2.7–5.5 V). The MC9S08DN16CLC datasheet specifies these values in Section 8.1.1 and Appendix A.

Does the MC9S08DN16CLC support LIN 2.0 communication natively?

Yes, the MC9S08DN16CLC includes SCI1 hardware that fully supports LIN 2.0 Protocol and SAE J2602 compliance. It provides dedicated features including master extended break generation, slave extended break detection, and wakeup on active edge - all implemented in hardware without CPU intervention. These capabilities are documented in Section 13 of the MC9S08DN16CLC datasheet and require no external transceiver for basic node operation.

How much EEPROM does the MC9S08DN16CLC provide, and what are its endurance specifications?

The MC9S08DN16CLC integrates 2 KB of on-chip EEPROM with in-circuit programmability. It supports 4-byte dual-page or 8-byte single-page erase sectors and guarantees a minimum of 100,000 erase/write cycles per sector. Erase abort functionality allows interruption of ongoing operations, and program/erase can occur while executing Flash code. These characteristics are specified in Section 4.5 of the MC9S08DN16CLC datasheet.

What low-power modes are available on the MC9S08DN16CLC, and which peripherals remain active in Stop3 mode?

The MC9S08DN16CLC offers Stop3, Stop2, Wait, and Run modes. In Stop3 mode - the deepest sleep state - only the Real-Time Interrupt (RTI) module, Low-Voltage Detect (LVD), and internal 1-kHz COP clock remain active. All other clocks are gated, CPU and peripherals halt, yet RTC and RTI retain functionality for timed wake-up. This behavior is detailed in Section 3.6.1 and Table 3-2 of the MC9S08DN16CLC datasheet.

Is the MC9S08DN16CLC pin-compatible with other members of the DN-series such as MC9S08DN32CLC or MC9S08DN48CLC?

Yes, the MC9S08DN16CLC in the 48-pin LQFP package shares identical pinout, electrical characteristics, and peripheral mapping with MC9S08DN32CLC and MC9S08DN48CLC in the same package variant. This allows direct substitution in existing designs where Flash size requirements permit - confirmed by Freescale's MC9S08DN60 Series Data Sheet Rev 3, Section 1.1 and Appendix C mechanical drawings.
