It integrates a direct LCD segment driver, low-voltage detect, power-on reset, PWM timers, and a watchdog timer, plus serial connectivity via I2C, SCI, and SPI. An internal oscillator and a 10-channel 12-bit ADC round out the peripheral set. The device is housed in an 80-LQFP (14x14 mm) surface-mount package and operates from 1.8 V to 3.6 V over -40°C to 85°C. ## Peripheral set and application fit The LCD driver is the distinguishing peripheral — it drives segment LCD panels directly without an external controller, making this MCU a natural fit for handheld instruments, metering panels, and white-goods displays. The 10-channel 12-bit ADC handles analog sensor inputs (temperature, pressure, current sense) with 39 available GPIOs for keypads, backlight control, and general-purpose I/O. The combination of LVD, POR, and WDT supports unsupervised operation in industrial and outdoor environments. ## Memory and speed — sizing the headroom 64 KB of Flash is a comfortable fit for mid-complexity firmware with a segmented LCD driver stack, a communication protocol (e.g., Modbus over SCI), and a simple RTOS or state machine. The 40 MHz core delivers roughly 40 MIPS for 8-bit operations — enough for real-time display refresh, ADC sampling at several ksps, and serial polling without stalling. The 4 KB RAM is the tighter resource: budget about 2 KB for stack and variables, leaving the rest for display buffers and communication frames. ## Lifecycle and compliance The MC9S08LL64CLK is listed as Active with RoHS3 compliance. No end-of-life notice or last-time-buy window has been announced.","metaTitle":"NXP MC9S08LL64CLK MCU, S08 8-bit, 40 MHz, 64 KB Flash","metaDescription":"NXP MC9S08LL64CLK 8-bit MCU, S08 core at 40 MHz, 64 KB Flash, 4 KB RAM, LCD driver, 12-bit ADC, -40 to 85°C.
