The IN6008 is low cost, high-performance, CMOS, fully-static, 8-bit microcontroller. The device has enhanced core

features, eight-level deep stack and multiple internal and external interrupt sources. The separate instruction and

data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The

two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches,

which require two cycles. A total of 35 instructions (reduced instruction set) are available. Additionally, a large

register set gives some of the architectural innovations used to achieve a very high performance.

The device has 22 I/O pins, 256 bytes of RAM. In addition, several peripheral features are available including:

three timer/counters, two Capture/Compare/PWM modules and two serial ports. The Universal Serial Bus (USB

1.1) low speed peripheral provides bus communications. The Universal Synchronous Asynchronous Receiver

Transmitter (USART) is also known as the Serial Communications Interface or SCI. Also, a 5-channel high-speed

12-bit A/D is provided. The 12-bit resolution is ideally suited for applications requiring a low cost analog interface

(e.g., thermostat control, pressure sensing, etc.).

The device has special features to reduce external components, thus reducing cost, enhancing system reliability

and reducing power consumption. There are 3 oscillator options, of which EC is for the external regulated clock

source, HS is for the high speed crystals/resonators and INTOSC is for internal oscillator.

The SLEEP (power-down) feature provides a power-saving mode. The user can wake-up the chip from SLEEP

through several external and internal interrupts and RESETS.

A highly reliable Watchdog Timer (WDT), with a dedicated on-chip RC oscillator, provides protection against

software lock-up, and also provides one way of waking the device from SLEEP
