7.3.4 Serial Flash Interface

The DLPC23x-Q1 uses an external SPI serial flash memory device for configuration and operational data. The minimum supported size is 16 Mb. Larger devices can be required based on operation data and splash image size. The maximum supported size is 128 Mb. It must be noted that the system will support 256 Mb and 512 Mb devices, however, only the first 128 Mb of space are used.

The external serial flash device is supported on a single SPI interface and mostly complies with industry standard SPI flash protocol (See Figure 5-8). The Host will specify the maximum supported flash interface frequency (which can be based on device limits, system limits, and/or other factors) and the system will program the closest obtainable value less than or equal to this specified maximum.

The DLPC23x-Q1 ASIC flash must be connected to the designated SPI flash interface (FLSH_SPI_xxx) to enable support for system initialization, configuration, and operation.

The DLPC23x-Q1 must support any flash device that is compatible with the modes of operation, features, and performance as defined in this section.

Status register bit(7)Status register write protect (SRWP)
Status register bits(15:8) (expanded status register), or
Secondary Status register		The DLPC23x-Q1 supports multi-byte status registers, as well as separate, additional status registers, but only for specific devices/register addresses. The supported registers and addresses are specified in Table 7-3.
CAUTION:

The selected SPI flash device must block repeated status writes from being written to internal register. The boot application writes to the flash device status register once per 256 bytes during programming. Most flash devices discard status register writes when the status content does not change. Some flash parts, such as the Micron N25Q128A13ESFA0F, do not block status writes when the status data is repeated. This causes the status register to exceed its maximum write limit after several programming cycles, making them incompatible with the DLPC23x-Q1. Note that the main application does not write to the status register.

For each write operation, the DLPC23x-Q1 boot application executes the following:

  1. Write enable command
  2. Write status command (to unprotect memory)
  3. Read status command to poll the successful execution of the write status (repeated as needed)
  4. Write enable command
  5. Program or erase command
  6. Read status command (repeated as needed) to poll the successful execution of the program or erase operation
  7. Write disable command (during programming; this is not performed after erase command.)

For each write operation, the DLPC23x-Q1 main application executes the following:

  1. Write enable command
  2. Program or erase command
  3. Read status command (repeated as needed) to poll the successful execution of the program or erase operation
  4. Write disable command (during programming; this is not performed after erase command)

The specific instruction op-code and timing compatibility requirements are listed in Table 7-3 and Flash Interface Timing Requirements. Note that DLPC23x-Q1 does not read the flash’s full electronic signature ID and thus cannot automatically adapt protocol and clock rates based on the ID.

(1) System does not support Read op-codes being spread across more than one data line.
(2) Flash vendors have diverged in naming and controlling their various read capabilities. As such, the Host needs to be very careful to fully understand what is and what is not supported by the DLPC23x-Q1. In general, for the supported devices, the DLPC23x-Q1 only supports "Extended SPI" or "SPI Mode" (as defined in the various Flash Data Sheets). It does not support "Dual SPI Mode", "Quad SPI Mode", "QPI", "QPI Mode", "Dual QPI", "Quad QPI", "DTR", or "DDR". If uncertain, most devices will support "Fast Reads" in a manner that is consistent with the DLPC23x-Q1.

(1) Care must be used when considering Numonyx versions of Micron serial flash devices as they typically do not have the 4KB sector size needed to be DLPC23x-Q1 compatible.
(2) For any devices not listed on this table, special care must be taken to insure that the requirements shown in Table 7-2 and Table 7-3 are met.
(3) The boot application writes to the flash device status register once per 256 bytes during programming. Most flash devices discard status register writes when the status content does not change. Some flash parts, such as Micron N25Q128A13ESFA0F, do not block status writes when the status data is repeated. This causes the status register to exceed its maximum write limit after several programming cycles, making them incompatible with the DLPC23x-Q1. Note that the main application does not write to the status register.

While the DLPC23x-Q1 supports a variety of clock rates and read operation types, it does have a minimum flash read bandwidth requirement which is shown in Table 7-6. This minimum read bandwidth can be met in any number of different ways, with the variables being clock rate and read type. The Host is required to select a flash device which can meet this minimum read bandwidth using the DLPC23x-Q1 supported interface capabilities. It must be noted that the Host will specify to the system (through flash parameter) the maximum supported clock rate as well as the supported read types for their selected flash device, with which the DLPC23x-Q1 SW will automatically select an appropriate combination to maximize this bandwidth (which must at least meet the minimum bandwidth requirement assuming a solution exists per the specified parameters).
