The MC9S08LL16/8 helps you reach your target performance levels while minimizing power consumption in your design, demonstrating extreme energy efficiency for ultra-long operation in battery-powered applications. The S08LL16 (LL16) microcontroller offers two ultra-low-power stop modes, new low-power run and wait modes, six microsecond wake-up time, ultra-low-power external oscillator and clock gating registers to disable clocks to unused peripherals. Features * Up to 20 MHZ HCS08 CPU from 1.8V to 3.6V and across a temperature range of -40°C to +85°C * Two ultra-low-power stop modes * New low-power run and wait modes * Internal clock source (ICS) * Integrated LCD driver supports both standard 3V and 5V LCD glass * Configurable display for 8 x 24 or 4 x 28 segment display * LCD driver pins are muxed with GPIO and other functions * Up to 16 KB flash read/program/erase over full operating voltage and temperature * Analog-to-digital converter (ADC)?8-channel, 12-bit resolution * Timer?two 2-channel * Serial communications interface (SCI) * Analog comparator with selectable interrupt on rising, falling or either edge of comparator output * Serial peripheral interface (SPI)?one module with full-duplex or single-wire bidirectional * I²C with up to 100 kbps * 38 general purpose input/output (GPIO), two output-only pins * Single-wire background debug interface Applications * Battery-operated handheld devices * Portable health care devices * Thermostats * Alarms/clocks * Exercise equipment * Personal diagnostics * Calculators * Low-end utility metering * ZigBee nodes with display * Scrolling text displays * Small appliances 9S08LL16 Block Diagram Easy-to-Use Development Tools and Training -DEMO9S08LL16[1] Cost-effective demonstration kit includes the serial port and built-in USB-BDM cable for debugging and programming. This tool also has a lab that demonstrates the ultra-low-power benefits and LCD feature. -Integrated USB-to-BDM interface No USBMULTILINKBDME required - Integrated USB-to-BDM circuit In-circuit debugging & Flash programming Without emulation requirements of serial monitors or other debugging techniques in the industry. - Demo board can be powered by the USB circuit No need for external power supply. CodeWarrior Development Studio for Microcontrollers v6.2 Part number: CWX-HXX-SE Complimentary Special Edition with compiler sizes of 32K Single tool suite that supports software development for future migration opportunities for both 8bit or 32-bit and includes rapid application development tool, Processor Expert MC9S08LL16 Series Block Diagram Pin Assignments The L family has industry-leading LCD capabilities, including the ability to drive more segments with fewer pins (up to 8x mode). In addition, the S08LL family offers best-in-class, ultra-low-power performance. The L family will offer industry leading advanced key features for consumer and industrial markets Full range portfolio, with pin compatibility options and shared peripherals Frontplane and backplane reassignment simplifies PCB layout and EMI optimization LCD driver support for up to 8 backplanes to drive more segments with fewer pins LCD blink mode without waking up the controller, which lowers power consumption S08 LCD family offers best-in-class, ultra-low-power performance and contrast control LL16/8 offers Freescale?s ultra-low-power technology at 1.8V with winning features, such as 20MHz CPU, flash reprogramming and ADC accuracy. Intended for low-power and portable applications, such as thermostats and blood glucose meters. 9S08LL16 Features/Benefits 8 ch keyboard interrupt Up to 40 GPIOs Up to 16 LCD Pins Mux with GPIO LVI (low voltage inhibit) Time of Day module Internal Clock Source (ICS) FLL On chip oscillator External crystal support 2% accuracy over full operating range LCD driver Based on 8 backplanes 8x24 = 192 segments Based on 4 backplanes 4x28 = 112 segments Supply Voltage/Performance 1.8V to 3.6V Core 10Mhz bus Speed Development Tools On Chip ICE and 08BDM 9S08LL8 Features/Benefits 8 ch keyboard interrupt Up to 31 GPIOs Up to 16 LCD Pins Mux with GPIO LVI (low voltage inhibit) Time of Day module Internal Clock Source (ICS) FLL On chip oscillator External crystal support 2% accuracy over full operating range LCD driver Based on 8 backplanes 8x16 = 128segments Based on 4 backplanes 4x20 = 80 segments Regulated charge pump on LCD Supply Voltage/Performance 1.8V to 3.6V Core 10Mhz bus Speed Development Tools On Chip ICE and 08BDM Source: S08LL [2] CONTACT REQUEST If you want to know more about this Freescale product, please submit your request to Arrow Italy using this form [3].
