LC74772V集成电路（IC）的显示驱动器规格书PDF中文资料

LC74772V属于集成电路（IC）的显示驱动器。由安森美半导体制造生产的LC74772V显示驱动器显示驱动器是一种集成电路 (IC)，可在微处理器 (MPU)、微控制器 (MCU) 或其他电路系统之间提供转换、接口和控制，用于 LCD、LED、OLED、DLP、真空荧光和 AMOLED 等显示器。可能的通信接口和协议包括模拟、BCD、I2C、并行、串行、SMBus、SPI 和 QSPI。

Overview

The LC74772V is a CMOS LSI that implements on-screen display for camcorders. It displays characters and patterns in a camcorder viewfinder under microprocessor control. The LC74772V displays a 12  18 dot font with 256 characters.

Functions

• Screen format: 12 lines x 24 characters (up to 288 characters)

• Number of characters displayed: Up to 288 characters

• Character format: 12 (horizontal) x 18 (vertical) dots

• Number of characters in font: 256 characters

• Character sizes: Normal and double, specified in line units

• Display start position

• Horizontal: 64 positions

— Vertical: 64 positions

• Character reverse video function: Individual characters can be displayed in reverse video.

• Types of blinking: Two types with periods of 1.0 and 0.5 seconds, specifiable on a per character basis.

(Blinking has a 60 display on duty.)

(Four divisors: 1/25, 1/30, 1/50, 1/60)

• Outputs: R, G, B plus 2 output systems

Or: 4 output systems (character data and blanking data: 4 outputs each)

• External control input: 8-bit serial data input format.
