MC9S08LC60LK Description

By providing an integrated LCD controller with the low-power and feature-rich capabilities of the S08 family, the MC9S08LC60LK microcontroller broadens Freescale's 8-bit product line. The first LCD S08 8-bit microcontroller for battery-operated and portable applications is MC9S08LC60LK. The S08LC is a flash-based device with improved off-chip EEPROM emulation, eliminating the need for it and reducing both board area and cost. The MC9S08LC60LK was designed with high segment count and battery friendliness in mind. A larger segment display with up to 160 segments can accommodate a wide range of display needs by providing complete flexibility with a graphical display and enough memory to serve as an application and LCD controller without the additional cost of a dot matrix or "chip-on-glass."

S08 Central Processor Unit (CPU)

40 MHz (20 MHz bus) at >2.1V operation for 50 ns minimum instruction time

16 MHz (8 MHz bus) frequency at <2.1V

LCD Driver and Internal Charge Pump

The integrated LCD driver supports both standard 3V and 5V LCD glass

Configurable display for 4 x 40 or 3 x 41segment display

Automatic blink and refresh

Internal charge pump

Capable of running in STOP3 mode

Flash Memory

In-application re-programmability

Dual flash block for enhanced EEPROM emulation

Clock Source Options

Internal clock generator (ICG)

frequency-locked loop (FLL)

controlled by internal or external reference

Serial Communication Ports

Serial communications interface (SCI) module offering asynchronous communications

Serial peripheral interface (SPI) module

Full-duplex, 3-wire synchronous transfer

The maximum bit rate of 5 MHz for 10 MHz bus frequency

Inter-integrated Circuit (I2C) bus module

2-wire synchronous serial module to connect to the standard I2C bus

Designed to operate up to 100 kbps with maximum bus loading and timing

Keyboard Interrupts (KBI) and I/O

Up to 16 KBI with software selectable polarity on edge or edge/level modes

Analog Integration

8-channel, 12-bit ADC

Automatic compare function, software programmable for more significant than, equal to, or less than conditions

Temperature sensor

The internal bandgap reference channel

Trigger conversion using the real-time interrupt (RTI) counter

Analog comparator module

Option to compare to the internal reference

Output can be optionally routed to the timer/pulse width modulation module (TPM) as an input capture trigger

Timers

Programmable 16-bit TPM

Each channel can be independently programmed for:

Input capture

Output compare

Buffered, edge-aligned pulse width modulation (PWM)

Buffered center-aligned PWM

System Security Features

Watchdog computer operating reset adequately with the option to run from a dedicated 1 kHz internal clock source or from the bus clock

Low-voltage detection (LVD) generates reset, interrupt or flag with two software selectable trip points

A low-voltage warning sets a flag, with higher trip points than LVD
