Introduction - If you have any usage issues, please Google them yourself
CH451 is an integrated LED display driver and the keyboard scan control and monitoring of the P-chip multifunction peripherals. RC oscillator circuit built-CH451, you can directly drive an 8-bit dynamic digital tube or 64-bit LED, with a BCD decoder or decoding function, data can be left, shifted to right, left circle, right circle, the number of independent scintillation and other control functions. CH451-level built-in high-current drive, current paragraph not less than 30mA, the word current is not less than 160mA, and a brightness control 16 in keyboard control, the device built-in 64-key keyboard controller can achieve 8 × 8 scan matrix keyboard and built-to-jitter circuit may interrupt the provision of key release and key features such as flag the external interface, CH451 choose simple or 1-wire serial interface high-speed 4-wire serial interface, and built on power-on reset can be reset to provide high effective and efficient reduction of two low-level output, built-in watchd
