7.4.1 Serial Flash Interface

The DLPC2607 device uses an external SPI serial flash memory device for configuration support. The minimum required size depends on the desired minimum number of sequences, CMT tables, and splash options while the maximum supported is 16 Mb. Table 1 provides the list of the configuration options.

Table 1. Serial Flash Support Features by Density(1)

TARGET FLASH DENSITY (Mb) QUANTITY OF FEATURES THAT CAN BE SUPPORTED
OPTICAL TEST SPLASH SCREENS STANDARD SPLASH SCREENS SERIES DATA SECTOR UNIT DATA SECTOR ODM DATA SECTOR DLP DISPLAY SEQUENCES (2) CMT TABLES PER SEQUENCE (3)
4 Mb 0 1 1 1 1 16 7
8 Mb 0 3 1 1 1 16 7
16 Mb 1 4 1 1 1 16 7
(1) All rows in this table have passed DVT at TI.
(2) Assumes individual DLP display sequences are limited to 5 KB each
(3) An equal number of CMT tables are required for each sequence (CMT tables define the DeGamma Curve). The DLPC2607 device uses a single SPI, employing SPI mode 0 protocol, operating at a frequency of 33.3 MHz. It supports two independent SPI chip selects. However, the primary flash must be connected to SPI chip select 0 (SPICS0) because the auto-initialization routine is always executed from the device connected to this chip select. The auto-initialization routine executed from flash consists of the following:
  • The DLPC2607 device first uploads the size and location of the auto-initialization routine from address range 0x0000 through 0x0007 of the serial flash memory connected to SPICS0.
  • The DLPC2607 device then uploads the actual auto-initialization routine to its ICP program memory from the serial flash memory connected to SPICS0.
  • The DLPC2607 device then executes an auto-init routine, which includes uploading default control parameter values, uploading mailbox memory contents, turning on the sequence and LEDs, and then enabling the display.
  • Upon completion of the auto-initialization routine, the DLPC2607 signals INIT DONE with GPIO4_INTF.

The DLPC2607 device supports any flash device that is compatible with these modes of operation. However, the DLPC2607 device does not support the Normal (slow) Read Opcode, and thus cannot automatically adapt protocol and clock rate based on the flash’s electronic signature ID. The flash instead uses a fixed SPI clock and assumes certain attributes of the flash have been ensured by PCB design. The DLPC2607 device also assumes the flash supports address auto-incrementing for all read operations. Table 2 and Table 3 list the specific instruction OpCode and timing compatibility requirements for a DLPC2607 device compatible flash.

Table 2. SPI Flash Instruction OpCode and Timing Compatibility Requirements

SPI FLASH COMMAND OPCODE (hex) ADDRESS BYTES DUMMY BYTES MIN CLOCK RATE
Fast READ (single output) 0x0B 3 1 33.3 MHz
All others Can vary Can vary Can vary 33.3 MHz

Table 3. SPI Flash Key Timing Parameter Compatibility Requirements

MIN MAX UNIT
Minimum chip select high time 300 ns
Minimum output hold time 0 ns
Maximum output valid time 9 ns
Minimum data in setup time 5 ns
Minimum data in hold time 5 ns

The DLPC2607 device does not have any specific page, block, or sector size requirements, except that programming with the I2C interface requires the use of page mode programming. However, if the user would like to use a portion of the serial flash for storing external data (such as calibration data) with the I2C interface, then the minimum sector size must be considered as it drives minimum erase size. Note that use of serial flash for storing external data may impact the number of features that can be supported.

NOTE

The DLPC2607 device does not drive the HOLD (active low hold) or WP (active low write protect) pins on the flash device. Tie these pins to a logic high on the PCB with an external pullup.

The DLPC2607 device supports 1.8 V, 2.5 V, or 3.3 V serial flash devices. Some suggested devices would include the W25Q16DWSSIG or MX25U4035. If a different flash device is used, Table 4 lists the minimum performance specifications necessary.
