IC89LV52(51)A

Note:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. Minimum DC input voltage is 0.5V. During transitions, inputs may undershoot to 2. 0V for periods less than 20 ns. Maximum DC voltage on output pins is Vcc + 0.5V which may overshoot to Vcc + 2.0V for periods less than 20 ns.
3. Operating temperature is for commercial products only defined by this specification.

The ICSI IC89LV52(51)A is a high-performance microcontroller fabricated with high-density CMOS technology.

The CMOS IC89LV52A is functionally compatible with the NMOS Intel 8052(51) and Philips' 80C52(51) micro controller, but its VCC is 3.05V~3.6V .

The IC89LV52(51)A contains a 8K (4K) x 8 Flash; a 256 x 8 RAM (128 x 8 RAM); 32 I/O lines for either multiprocessor communications; I/O expansion or full duplex UART; three (two) 16-bit timers/counters; a six-source (five-source), two-priority-level, nested interrupt structure; and on chip oscillator and clock circuit.

The IC89LV52(51)A can be expanded using standard TTL compatible memory.
