NXP Semiconductors MC9S08LL16CGTR

Overview

MC9S08LL16CGTR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller designed for ultra-low-power LCD-based embedded applications. It delivers 20-MHz CPU operation across 1.8–3.6 V, integrates 16 KB dual-array FLASH and 2.08 KB RAM, and supports LCD drive up to 8×24 segments with internal charge pump and contrast trimming - deployed in battery-powered industrial meters and portable medical displays.

For engineers reviewing the MC9S08LL16CGTR datasheet, MC9S08LL16CGTR pinout, MC9S08LL16CGTR application, or MC9S08LL16CGTR equivalent, this page provides verified package mapping (48-pin QFN), confirmed low-power stop3 mode current (400–8000 nA), validated ADC specs (12-bit, 2.5 μs conversion), and real-world peripheral integration including SCI/LIN, I²C, SPI, TPM, TOD, and ACMP - all critical for energy-constrained UI and sensor interface designs.

Technical Context

The MC9S08LL16CGTR implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with factory-trimmed internal reference (±2% deviation over voltage/temperature), enabling stable 1–10 MHz bus frequencies without external crystal.

System-level power management includes three stop modes (Stop2/Stop3), low-power run/wait modes with peripheral clock gating, and a dedicated 1-kHz low-power oscillator for RTC wake-up. The analog subsystem features an 8-channel 12-bit ADC operating down to 1.8 V, an analog comparator with edge-selectable interrupt and bandgap reference, and integrated LCD driver supporting both 4×28 and 8×24 configurations with programmable VLCD regulation.

FAQ

What is the maximum operating frequency of the MC9S08LL16CGTR CPU?

The MC9S08LL16CGTR CPU operates at up to 20 MHz across its full voltage (1.8–3.6 V) and temperature (–40°C to +85°C) range. This frequency is achieved using the internal clock source (ICS) with FLL enabled and external crystal or resonator, or via internal reference trimming for crystal-free operation at lower bus speeds.

Does the MC9S08LL16CGTR support LCD drive without external components?

Yes, the MC9S08LL16CGTR integrates a full LCD driver supporting up to 8×24 segments with internal charge pump, programmable VLCD regulation, and software-trimmable contrast control. No external bias generator or charge pump IC is required - only standard LCD glass and decoupling capacitors.

What is the lowest power consumption mode of the MC9S08LL16CGTR?

The MC9S08LL16CGTR achieves its lowest power state in Stop3 mode, drawing 400 nA typical at –40°C to +25°C with only the 1-kHz low-power oscillator and Time-of-Day (TOD) module active. This enables multi-year battery operation in applications like utility meters and environmental sensors.

Can the MC9S08LL16CGTR perform ADC conversions while in low-power mode?

Yes, the MC9S08LL16CGTR's 12-bit ADC remains fully functional in Stop3 mode, allowing background sensor measurements without waking the CPU. Conversion time is 2.5 μs, and results can trigger interrupts or store directly to memory - essential for energy-efficient data acquisition.

Is the MC9S08LL16CGTR pin-compatible with other 48-pin QFN HCS08 MCUs?

The MC9S08LL16CGTR shares the same 48-pin QFN footprint (98ASA00466D) and pin assignments as MC9S08AC16, MC9S08JM16, and MC9S08GT16A per Freescale's QFN Addendum Rev. 0. However, peripheral mapping (e.g., LCD pins, TOD) differs - PCB layout reuse requires verification against each device's specific pin function table.
