Part Number : LC7234
Function : Singl-chip PLL and Microcontroller with LCD Driver
Package : QIP 64 Pin Type
Manufacturers : SANYO ( Panasonic )
The LC7234 is a single-chip microcontroller that incorporates a 0.5 to 150MHz phase-locked loop (PLL) and a liquid-crystal display (LCD) driver, making it ideal for digital tuners. It has a large number of input/output ports and a frequency measurement circuit. The LC7234 freatures on-chip RAM and ROM, a program mable high-speed divider, a 6-bit analog-to-digital converter and a low-voltage detection reset circuit. The LC7234 operates from a 5V supply and is available in 64-pin QIPs.
