SM320VC33 SMJ320VC33 test_load_circuit_SGUS034.gif

WHERE:

  • IOL = 4 mA (all outputs) for dc levels test.
  • IO and IOH are adjusted during ac timing analysis to achieve an ac termination of 50 Ω
  • VLOAD = DVDD / 2
  • CT = 40-pF typical load-circuit capacitance

SM320VC33 SMJ320VC33 output_load_charact_buf_only_SGUS034.gif
This figure shows output load characteristics for high-speed and low-speed (low-noise) output buffers. High-speed buffers are used on A0 to A23, PAGE0 to PAGE3, H1, H3, STRB, and R/W. All other outputs use the low-speed, (low-noise) output buffer.
CLmax = 30 pF

SM320VC33 SMJ320VC33 reset_timing_SGUS034.gif
  1. Clock circuit is configured in C31-compatible divide-by-2 mode. If configured for x1 mode, EXTCLK directly drives H3.
  2. Asynchronous reset signals include XF0/1, CLKX0, DX0, FSX0, CLKR0, DR0, FSR0, and TCLK0/1.
  3. RESET is a synchronous input that can be asserted at any point during a clock cycle. If the specified timings are met, the exact sequence shown occurs; otherwise, an additional delay of one clock cycle is possible.
In microprocessor mode, the reset vector is fetched twice, with seven software wait states each time. In microcomputer mode, the reset vector is fetched twice, with no software wait states.
The address and PAGE3 to PAGE0 outputs are placed in a high-impedance state during reset requiring a nominal 10- to 22-kΩ pullup. If not, undesirable spurious reads can occur when these outputs are not driven.

  1. Falling edge of H1 just detects INTx falling edge.
  2. Falling edge of H1 detects second INTx low, however flag clear takes precedence.

  4. Falling edge of H1 misses previous INTx low as INTx rises.
