6.14 Flash Interface Timing Requirements

The DLPC34xx flash memory interface consists of a SPI flash serial interface with a programmable clock rate. The DLPC34x6 can support 1- to 128-Mb flash memories.(2)(3)(4)
MIN MAX UNIT
fclock SPI_CLK frequency See (1) 1.4 36.0 MHz
tp_clkper SPI_CLK period 50% reference points 27.8 704 ns
tp_wh SPI_CLK pulse duration high 50% reference points 352 ns
tp_wl SPI_CLK pulse duration low 50% reference points 352 ns
tt Transition time – all signals 20% to 80% reference points (rising signal)
80% to 20% reference points (falling signal)		 0.2 3.0 ns
tp_su Setup time – SPI_DIN valid before SPI_CLK falling edge 50% reference points 10.0 ns
tp_h Hold time – SPI_DIN valid after SPI_CLK falling edge 50% reference points 0.0 ns
tp_clqv SPI_CLK clock falling edge to output valid time – SPI_DOUT and SPI_CSZ 50% reference points 1.0 ns
tp_clqx SPI_CLK clock falling edge output hold time – SPI_DOUT and SPI_CSZ 50% reference points –3.0 3.0 ns
(1) This range include the ±200 ppm of the external oscillator (but no jitter).
(2) Standard SPI protocol is to transmit data on the falling edge of SPI_CLK and capture data on the rising edge. The DLPC34x6 transmits data on the falling edge, but it also captures data on the falling edge rather than the rising edge. This provides support for SPI devices with long clock-to-Q timing. DLPC34xx hold capture timing has been set to facilitate reliable operation with standard external SPI protocol devices.
(3) With the above output timing, DLPC34xx provides the external SPI device 8.2-ns input set-up and 8.2-ns input hold, relative to the rising edge of SPI_CLK.
(4) For additional requirements of the external flash device, view the Section 7.3.3.1 section.
