TC820CPL集成電路（IC）的顯示驅(qū)動器規(guī)格書PDF中文資料

TC820CPL屬于集成電路（IC）的顯示驅(qū)動器。由微芯科技股份有限公司制造生產(chǎn)的TC820CPL顯示驅(qū)動器顯示驅(qū)動器是一種集成電路 (IC)，可在微處理器 (MPU)、微控制器 (MCU) 或其他電路系統(tǒng)之間提供轉(zhuǎn)換、接口和控制，用于 LCD、LED、OLED、DLP、真空熒光和 AMOLED 等顯示器。可能的通信接口和協(xié)議包括模擬、BCD、I2C、并行、串行、SMBus、SPI 和 QSPI。

GENERAL DESCRIPTION

The TC820 is a 3-3/4 digit, multi-measurement system especially suited for use in portable instruments. It integrates a dual slope A/D converter, auto-ranging frequency counter and logic probe into a single 44-pin surface mount or 40-pin through hole package. The TC820 operates from a single 9V input voltage (battery) and features a built-in battery low flag. Function and decimal point selection are accomplished with simple logic inputs designed for direct connection to an external microcontroller or rotary switch. Ease of use, low power operation and high functional integration make the TC820 desirable in a variety of analog measurement applications.
