7.2. Panel Supply Switch Circuit
This switch is used to open and close panel supply of TCON. It is controlled by port of main
ucontroller. Also with this circit panel sequency could be adjusted correctly. 3 panel supplys
are connected to this circuit. All of them are optional according to panels.
8. SPI FLASH MEMORY
8.1 EN25Q64 64 Megabit Serial Flash Memory with 4Kbyte Uniform
Sector
8.1.1 General Description
The EN25Q64 is a 64 Megabit (8192K-byte) Serial Flash memory, with advanced write
protection mechanisms. The EN25Q64 supports the standard Serial Peripheral Interface
(SPI), and a high performance Dual output as well as Quad I/O using SPI pins: Serial
Clock, Chip Select, Serial DQ0(DI), DQ1(DO), DQ2(WP#) and DQ3(NC). SPI clock
frequencies of up to 50MHz are supported allowing equivalent clock rates of 100MHz for
Dual Output and 200MHz for Quad Output when using the Dual/Quad Output Fast Read
instructions. The memory can be programmed 1 to 256 bytes at a time, using the Page
Program instruction. The EN25Q64 is designed to allow either single Sector/Block at a time
or full chip erase operation. The EN25Q64 can be configured to protect part of the memory
as the software protected mode. The device can sustain a minimum of 100K program/erase
cycles on each sector or block.
