Product details
Overview
MC9S08FL8CLC from NXP Semiconductors (formerly Freescale) is an 8-bit S08 microcontroller with 8 KB flash, 768-byte RAM, and integrated peripherals including 12-channel 8-bit ADC, dual TPM modules, SCI, and 16-bit modulo timer. It operates up to 20 MHz at 4.5–5.5 V across –40 °C to +85 °C and supports low-power stop modes for battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the MC9S08FL8CLC datasheet, MC9S08FL8CLC pinout, MC9S08FL8CLC application, or MC9S08FL8CLC equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use scenarios, and validated alternative parts - all grounded in the official MC9S08FL16 Series Data Sheet Rev. 4 (May 2015), which explicitly covers MC9S08FL8.
Technical Context
The MC9S08FL8CLC implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and nested priority via IPC. Its clock system combines internal ICS (FLL-based, 31.25 kHz internal reference, ±2% deviation over voltage/temperature) and external XOSC (1–16 MHz crystal/resonator support).
Peripherals include a 12-channel 8-bit ADC with 2.5 μs conversion time, temperature sensor (1.7 mV/°C), and bandgap reference; two TPM modules (4-channel + 2-channel) with PWM, input capture, and output compare; one 16-bit modulo timer; and one SCI with LIN extensions. All operate within 4.5–5.5 V supply range.

FAQ
What is the maximum operating frequency of the MC9S08FL8CLC?
The MC9S08FL8CLC supports a maximum bus frequency of 10 MHz, enabling a 20 MHz CPU clock via internal divide-by-2. This is guaranteed across the full operating voltage range (4.5–5.5 V) and temperature range (–40 °C to +85 °C), as specified in the MC9S08FL16 Series Data Sheet Rev. 4 covering MC9S08FL8.
Does the MC9S08FL8CLC support in-circuit debugging?
Yes, the MC9S08FL8CLC features a single-wire background debug interface (BKGD/MS pin) with on-chip in-circuit emulator (ICE) support, including two comparators and nine trigger modes. This allows full real-time debugging, breakpoint setting, and flash programming without requiring external JTAG hardware.
What are the memory resources of the MC9S08FL8CLC?
The MC9S08FL8CLC integrates 8 KB of user flash memory (read/program/erase over full voltage and temperature) and 768 bytes of RAM. Flash security circuitry prevents unauthorized access, and memory mapping follows the S08 architecture with direct-page (0x0000–0x003F) and high-page (0x1800–0x187F) register regions.
Which package options are available for the MC9S08FL8CLC?
The MC9S08FL8CLC is offered in two RoHS-compliant packages: 32-pin SDIP (mechanical drawing 1376-02) and 32-pin LQFP (873A-03). Both share identical pin assignments, electrical characteristics, and thermal resistance values (θJA = 60 °C/W for SDIP, 85 °C/W for LQFP on single-layer board).
Can the MC9S08FL8CLC operate in low-power modes?
Yes, the MC9S08FL8CLC supports multiple low-power modes: Wait mode (2.79 μA typical at 10 MHz), Stop2 (1.06 μA), and Stop3 (1.17 μA). In Stop3, optional peripherals like ADC, ICS, and LVD can remain active with defined current adders - enabling wake-on-event functionality in battery-powered applications.
