Product details
Overview
MC9S08EL16CTL from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip FLASH, 1 KB RAM, and 512 B EEPROM; features 10-bit ADC, dual analog comparators, LIN-capable SLIC, SCI, SPI, I²C, two TPM modules, RTC, and 22 GPIO pins in a 28-pin TSSOP package; used in automotive body electronics and industrial control nodes requiring LIN communication and low-power operation.
For engineers reviewing the MC9S08EL16CTL datasheet, MC9S08EL16CTL pinout, MC9S08EL16CTL application, or MC9S08EL16CTL equivalent, key selection criteria include its 28-TSSOP footprint, 16 KB FLASH/1 KB RAM memory partition, LIN 2.0-compliant SLIC peripheral, stop3-mode operation down to 1 kHz RTC wake-up, and single-wire background debug interface compatibility.
Technical Context
The MC9S08EL16CTL implements the HCS08 CPU core running at up to 40 MHz with HC08 instruction set extension (BGND), supporting up to 32 interrupt/reset sources and featuring a frequency-locked loop (FLL)-based internal clock source (ICS) with ±2% accuracy over voltage and temperature. Its memory subsystem includes FLASH with sector protection, in-circuit programmable EEPROM with erase-abort capability, and security circuitry preventing unauthorized access.
Peripherals are optimized for automotive body control: SLIC handles full LIN 2.0 message buffering and checksum verification at up to 120 kbps; dual ACMPs support bandgap-referenced voltage monitoring with output routing to TPM; ADC runs in stop3 mode with temperature sensor and automatic compare function; RTC uses internal 1-kHz oscillator for cyclic wake-up without external components.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08EL32CTL | 32 KB FLASH, 2 KB RAM, same peripherals and pinout; identical 28-TSSOP package and SLIC/ADC/TPM register mapping | Required where firmware image size exceeds 16 KB or additional RAM is needed for complex LIN message buffering or diagnostics | Select MC9S08EL32CTL when future firmware expansion headroom or larger runtime data buffers are required; drop-in replacement with no PCB change |

FAQ
What is the maximum bus frequency supported by the MC9S08EL16CTL?
The MC9S08EL16CTL supports a maximum bus frequency of 20 MHz when using the internal clock source (ICS) with FLL enabled, or up to 40 MHz when driven by an external crystal oscillator. This allows real-time execution of LIN protocol timing constraints and fast ADC sampling without compromising system responsiveness. The MC9S08EL16CTL's clock architecture ensures stable operation across automotive temperature ranges.
Does the MC9S08EL16CTL include hardware support for LIN communication?
Yes, the MC9S08EL16CTL integrates a dedicated Slave LIN Interface Controller (SLIC) compliant with LIN 2.0 and SAE J2602 standards. It handles automatic bit-rate synchronization, checksum generation/verification, full message buffering, and extended break detection-offloading 100% of LIN protocol processing from the CPU. This hardware acceleration is confirmed in the official MC9S08EL32/EL16 data sheet Rev. 3.
Can the MC9S08EL16CTL operate in low-power modes while maintaining real-time wake-up capability?
Yes, the MC9S08EL16CTL supports stop3 mode, where the CPU and most peripherals halt while the RTC continues running from an internal 1-kHz oscillator. This enables deterministic wake-up intervals (e.g., every 100 ms for sensor polling) without external crystals or clocks. The MC9S08EL16CTL's stop3 mode achieves sub-5 µA typical current draw, validated in Freescale's electrical characteristics appendix.
What analog peripherals are integrated into the MC9S08EL16CTL?
The MC9S08EL16CTL integrates a 10-bit, 16-channel ADC with 2.5 µs conversion time, internal temperature sensor, and bandgap reference channel; plus two 5-V analog comparators (ACMP) with selectable interrupt edges and bandgap reference option. Both ADC and ACMP operate in stop3 mode, enabling low-power analog monitoring. These peripherals are fully documented in Chapters 10 and 9 of the MC9S08EL32/EL16 data sheet.
Is the MC9S08EL16CTL pin-compatible with other devices in the HCS08 EL series?
Yes, the MC9S08EL16CTL in 28-TSSOP is pin-compatible with the MC9S08EL32CTL and shares identical pin assignments, peripheral mappings, and electrical characteristics. This allows direct substitution in existing designs when firmware size or RAM requirements increase. The shared package and register-level compatibility are explicitly confirmed in the "Package Options" section of the MC9S08EL32/EL16 data sheet Rev. 3.
