The LC60 is based on the S08 CPU architecture. This offers the benefits of high-performance, greater C-compiler efficiency, and a low-voltage, battery-operated system topology. The operating voltage for the LC60 is between 1.8 and 3.6 volts. The core can run up to 20 MHz when the voltage is at 3.6 volts. This device also supports up to 60K of flash with dual flash arrays that can execute from one block while writing to or erasing from another without having to wait for the erase to finish. Also, the flash on the LC60 allows programming all the way down to 1.8 volts. Additionally, the LC60 uses an internal clock and timer module, which allows a maximum bus speed of up to 20 MHz. An oscillator is also included, which can interface to external clock sources for applications that need additional accuracy for time of day (e.g., an alarm clock). Serial communication programs supported by the LC60 are SCI, STI, and I²C. STI allows seamless interface to ZigBee devices and other low power radios for network applications. One important note in the I²C is that the specification mentions operation up to 100 kilobits per second; however, that considers maximum bus loading and timing. With reduced bus loading, the I²C can achieve higher baud rates. The LC60 also has NXP’s fastest, lowest power, and most accurate 12-bit analog-to-digital converter, allowing for an easy interface to analog components like temperature and pressure sensors. Additionally, the built-in background debugging module makes debugging designs a lot easier, along with eliminating the need for extensive emulation hardware. Finally, the LC60 comes in two packages: the 64LQFP and 80LQFP. The built-in internal charge pump reduces the number of external components on the board, thereby saving costs and reducing the design complexity. Also, the LC60 allows supply voltage on the LVCD pin. This voltage is used to generate the bias voltages needed to drive an LCD. This device supports both 3V and 5V glass, thus offering flexibility with glass selection. Additionally, the LC60 has an automatic blink capability which is programmable for the entire display or individual segments, and is available in the stop mode.
