W78E354 chip decryption

Posted by

W78E354 chip WINBOND (Hua Bang) company’s typical OTP microcontroller, at present, Flying Star chip decryption Research Institute in the W78E series chip decryption technology research has made a series of technical research results, can provide a safe and reliable, reasonable price, cost cycle strict control decryption scheme for all types of customers.
Next, we will give a brief introduction to the W78E354 chip for reference to customers and decryption engineers.
W78E354 is a separate high-performance microcontroller ASIC designed specifically for use in display control applications. Using the Huabang 0.8m DPDM process, W78E354 integrates an embedded 8031 microcontroller kernel, 16K bytes of flash memory, 512 bytes of RAM, and some dedicated hardware functions. These hardware features include a 6-bit A/D converter, two PWM static D AC/1412/8-bit, one/three PWM dynamic D AC 12/8-bit, synchronous processor, a DDC port, watchdog timer, and other custom gluing logic. Additional special function registers are incorporated into the control peripheral hardware.
The chip is used to control the interface signals of the monitor and other devices and process the video synchronization signals. Because of the high integration and the establishment of flash memory units, the device provides users with a low-cost competitive advantage and shorter development time.
