It features a 12-bit ADC (12 channels), dual TPM modules (2+6 channels), I²C, SPI, SCI, RTC, and low-power stop3 mode with 100 µs wakeup - deployed in automotive instrument clusters and industrial panel meters.

For engineers reviewing the S9S08LG16J0CLH datasheet, S9S08LG16J0CLH pinout, S9S08LG16J0CLH application, or S9S08LG16J0CLH equivalent, key selection criteria include its 48-pin LQFP package, 2.7–5.5 V operation, I²C up to 100 kbps, 12-bit ADC with internal bandgap reference, and support for LIN-compliant SCI interfaces in automotive-grade temperature range (–40 °C to +105 °C).

Technical Context

The S9S08LG16J0CLH implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its clock system integrates both an external crystal oscillator (XOSC, 31.25 kHz–16 MHz) and an internal clock source (ICS) with FLL, enabling bus frequencies from 1 MHz to 20 MHz with ±2% deviation over voltage and temperature.

Peripherals include a dedicated LCD controller with internal charge pump, a 12-channel 12-bit ADC operating down to 2.7 V with temperature sensor and automatic compare, and two timer/PWM modules (TPM1: 2-channel; TPM2: 6-channel) supporting input capture, output compare, and center-aligned PWM - all functional in stop3 mode with wake-up capability.

FAQ

What is the maximum operating frequency of the S9S08LG16J0CLH CPU core?

The S9S08LG16J0CLH HCS08 CPU operates at up to 40 MHz when supplied at 5.5 V across the full temperature range (–40 °C to +105 °C). At lower supply voltages (e.g., 3.3 V), maximum frequency is reduced per the device's voltage-frequency specification - confirmed in Table 11 (ICS Frequency Specifications) of the MC9S08LG32 Series Data Sheet Rev. 9. The S9S08LG16J0CLH achieves this via its internal clock source (ICS) with FLL and external crystal oscillator (XOSC) options.

Does the S9S08LG16J0CLH support LIN communication?

Yes, the S9S08LG16J0CLH supports LIN communication through its SCI1 and SCI2 modules, which implement LIN master extended break generation and LIN slave extended break detection per the MC9S08LG32 Series Data Sheet Rev. 9. Both SCI interfaces also provide wakeup-on-active-edge functionality - essential for low-power LIN node operation. The S9S08LG16J0CLH does not integrate a LIN transceiver; external PHY is required.

What LCD configurations are supported by the S9S08LG16J0CLH in its 48-pin LQFP package?

In the 48-pin LQFP package, the S9S08LG16J0CLH supports up to 4×33 or 8×21 LCD segments, as specified in Table 1 of the MC9S08LG32 Series Data Sheet Rev. 9. This is fewer than the 8×29/4×33 capability of the 64-pin variant due to reduced pin count - with PTE and PTG port pins (used for higher-segment counts) omitted. The S9S08LG16J0CLH retains the internal charge pump and LCD bias generation circuitry required for direct glass drive.

Is the S9S08LG16J0CLH pin-compatible with the MC9S08LG32J0CLH?

No, the S9S08LG16J0CLH is not pin-compatible with the MC9S08LG32J0CLH. The S9S08LG16J0CLH uses a 48-pin LQFP package (Case 932), while the MC9S08LG32J0CLH is offered in 64-pin and 80-pin LQFP packages only - with different pin assignments, peripheral mappings, and I/O counts. Migration between them requires PCB redesign. The S9S08LG16J0CLH shares the same core architecture and peripheral set but is physically distinct.

What debug interface does the S9S08LG16J0CLH provide?

The S9S08LG16J0CLH provides a single-wire background debug (BKGD) interface on the PTC5 pin, supporting in-circuit debugging, flash programming, and breakpoint setting via the on-chip debug module. It includes three comparators, nine trigger modes, and an eight-deep FIFO for change-of-flow addresses - fully documented in the "Development Support" section of the MC9S08LG32 Series Data Sheet Rev. 9. The S9S08LG16J0CLH does not support JTAG or SWD.
