Character adder DP7456 chip replaces MAX7456EUI
First, the origin of the DP7456 chip:
The DP7456 is an alternative to the MAX7456, a full PIN-to-PIN video character overlay chip (OSD). In comparison with the performance of the MAX7456, in the register operation, the DP7456 is slower when reading, and the writing is faster, and the DP7456 consumes less power than the MAX7456. In terms of production process, the DP7456 has more ground wire than the MAX7456 to dissipate heat, and the 27M clock DP7456 is more accurate than the MAX7456. The rest are almost the same, and the price/performance ratio is far lower than the MAX7456.
Second, the function of the DP7456 chip is summarized:
The DP7456 is a single-channel, monochrome on-screen display generator with integrated EEPROM. It integrates a video driver, sync separator, video separation switch and EEPROM to improve system integration and reduce system cost.
The DP7456 is available in NTSC and PAL formats with 256 user-programmable characters for the global market.
The DP7456 can easily display a variety of information in any character or size, such as company logo, common graphics, time, date, and more.
The DP7456 is preloaded with 256 characters and graphics and can be programmed online via the SPI-compatible serial interface.
The DP7456 is available in a 28-pin TSSOP package and operates over the -40°C to +85°C temperature range.
Third, the mass production time of DP7456: May 06, 2013
Fourth, DP7456 manufacturers and agency qualifications:
The DP7456 manufacturer is produced by Hangzhou Zhongke Microelectronics Co., Ltd., a national high-tech enterprise and an integrated circuit design enterprise recognized by the Ministry of Industry and Information Technology. It is an agent of Shenzhen Kinergy Century Technology Co., Ltd.
