Features, Applications

Specification

* Operating voltage 2.5V-4.5V * Dual operation frequencies - 32.768 KHz for LCD & 0.5 second timer interrupt. - Built-in PLL circuit to generate system clock. * Built-in 2K bytes RAM. * Built in 192x8 display RAM for LCD data. * Built-in 512K bytes ROM with 16K bytes per bank. * External memory can be expanded to two 1M bytes ROM/RAM with 16K bytes per bank. * One 0.5 second pre-divider timer interrupt with start/stop control. * I/O ports - 14 pins shared with address bus for keyboard output port 1 and port - 4 input pins with wake-up interrupt for port 3. Pull-up resistors are built-in for this port. - 8 I/O pins shared with D0-D7 for port - 8 I/O pins for port * 8-bit auto-reloadable timer with 8 predefined input clocks. * 8-bit sound generator with 8 predefined input clocks. * LCD display : 48 segments, 32 commons, 1/5 bias, 1/32 duty and 64 Hz frame frequency. * 16 contrast levels for LCD display * One output for the speaker. - 2 KHz or 4 KHz signal with two different envelopes are selectable for sound output. * One UART serial port with even parity bit and one stop bit added after MSB. A carrier generator is also built-in. * The internal ROM can be disabled and the corresponding memory area is mapped to the highest banks of external ROM. * Sleep mode : LCD off , crystal & system oscillator stop, Vdd=3V, Idd < 1 µA. Stand-by mode : LCD on and system oscillator stop, Vdd=3V, Idd < 200 µA. LCD off and system oscillator stop, Vdd=3V, Idd < 10 µA.

* Code option - 150K OHM Pull-up resistor for P40-P47 and RC or crystal oscillation for 32768Hz clock.

AL8805 : LED Driver With Internal Switch The AL8805 is a step-down DC/DC converter designed to drive LEDs with a constant current. The device can drive up to 8 LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 6V to 30V. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating.
