MC9S08Lx系列是Freescale 公司的集成了LCD驅動器的超低功耗MCU,同時增加了ADC的精度以用于醫療和儀表測控應用. MC9S08LH采用8位HCS08 CPU,有高達64KB的閃存,3.6V-2.1V電壓時CPU頻率高達40MHz,支持多達32個中斷源,帶電荷泵的多達8x36或4x40 LCD驅動器以及16位分辨率的ADC,主要應用在汽車電子,消費類電子,智能電表,工業控制,醫療和馬達控制.本文介紹了MC9S08LH64系列主要特性,方框圖以及TWR-S08LH64-KIT開發套件主要特性和開發板電路圖.
Freescale expands the first S08 ultra-low-power MCU with LCD driver and increased ADC accuracy for medical and metering applications. The MC9S08LH family available with up to 64KB flash 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.
Maximize battery life, measure more precisely and make development easier with Freescale’s MC9S08LH64/36. The 16-bit SAR delivers outstanding precision to meet the needs of entry-level metering and medical applications.
Cost is reduced with the integration of an LCD driver which supports more segments with fewer pins. Additionally, the MCU is the industry’s best-in-class ultra-low-power MCU with LCD for long operation in batterypowered applications. These features are ideal for smart metering and medical applications such as glucometers and pulse oximeters.
Provides entry level flash-size part (64 KB) for cost-conscious, single-phase, electricity meter designs. The enhanced ADC, along with low-power technology, is ideal for electricity meters and medical devices operated by battery for more than five years.
MC9S08LH64系列主要特性:
Covers: MC9S08LH64 and MC9S08LH36
? 8-Bit HCS08 Central Processor Unit (CPU)
– Up to 40 MHz CPU at 3.6 V to 2.1 V across temperature range of –40℃ to 85℃
– Up to 20 MHz at 2.1 V to 1.8 V across temperature range of –40℃ to 85℃
HC08 instruction set with added BGND instruction
– Support for up to 32 interrupt/reset sources
? On-Chip Memory
– Dual array flash read/program/erase over full operating voltage and temperature
– Random-access memory (RAM)
– Security circuitry to prevent unauthorized access to RAM and flash contents
? Power-Saving Modes
– Two low-power stop modes
– Reduced-power wait mode
Low-power run and wait modes allow peripherals to run while voltage regulator is in standby
– Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents
– Very low-power external oscillator that can be used in stop2 or stop3 modes to provide accurate clock source to time-of-day (TOD) module
– 6 μs typical wakeup time from stop3 mode
? Clock Source Options
– Oscillator (XOSC) — Loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz
– Internal Clock Source (ICS)—Internal clock source module containing a frequency-locked-loop (FLL) controlled by internal or external reference; precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage; supporting bus frequencies from 1 MHz to 20 MHz
? System Protection
– Watchdog computer operating properly (COP) reset with option to run from dedicated 1 kHz internal clock source or bus clock
– Low-voltage warning with interrupt
– Low-voltage detection with reset or interrupt
– Illegal opcode detection with reset; illegal address detection with reset
Flash block protection
? Development Support
– Single-wire background debug interface
– Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module)
– On-chip in-circuit emulator (ICE) debug module containing three comparators and nine trigger modes
? Peripherals
– LCD — Up to 8×36 or 4×40 LCD driver with internal charge pump and option to provide an internally-regulated LCD reference that can be trimmed for contrast control
– ADC —16-bit resolution; with a dedicated differential ADC input, and 8 single-ended ADC inputs; up to 2.5 μs conversion time; hardware averaging; calibration registers, automatic compare function; temperature sensor; operation in stop3; fully functional from 3.6 V to 1.8 V
– IIC — Inter-integrated circuit bus module to operate at up to 100 kbps with maximum bus loading; multi-master operation; programmable slave address; interrupt-driven byte-by-byte data transfer; broadcast mode; 10-bit addressing
– ACMP — Analog comparator with selectable interrupt on rising, falling, or either edge of comparator output; compare option to fixed internal reference voltage; outputs can be
optionally routed to TPM module; operation in stop3
– SCIx — Two full-duplex non-return to zero (NRZ) modules (SCI1 and SCI2); LIN master extended break generation; LIN slave extended break detection; wakeup on active edge
– SPI — Full-duplex or single-wire bidirectional; double-buffered transmit and receive; master or slave mode; MSB-first or LSB-first shifting
– TPMx — Two 2-channel (TPM1 and TPM2); selectable input capture, output compare, or buffered edge- or center-aligned PWM on each channel
– TOD — (Time-of-day) 8-bit, quarter second counter with match register; external clock source for precise time base, time-of-day, calendar, or task scheduling functions
– VREFx—Trimmable via an 8-bit register in 0.5 mV steps; automatically loaded with room temperature value upon reset; can be enabled to operate in stop3 mode; trim register is not available in stop modes
? Input/Output
– Dedicated accurate voltage reference output pin, 1.2 V output (VREFOx); trimmable with 0.5 mV resolution
– Up to 39 GPIOs, two output-only pins
– Hysteresis and configurable pullup device on all input pins; configurable slew rate and drive strength on all output pins
? Package Options: 14mm × 14mm 80-pin LQFP, 10 mm × 10 mm 64-pin LQFP
