• Manufacturer: Emlsi Inc.

Table 11: Partial-Array Refresh Specifications and Conditions
Note: IPAR (MAX) values measured at 85°C. IPAR might be slightly higher for up to 500 ms after changes to the PAR array partition or when entering
standby mode.
Table 12: Capacitance
Note: 1. These parameters are verified in device characterization and are not 100% tested.
Figure 20: AC Input/Output Reference Waveform
Note:
1. AC test inputs are driven at VCCQ for a logic 1 and VSSQ for a logic 0. Input rise and fall times (10% to 90%) <1.6ns.
2. Input timing begins at VCCQ/2.
3. Output timing ends at VCCQ/2.
Figure 21: AC Output Load Circuit
Note: All tests are performed with the outputs configured for default setting of half drive strength (BCR[5:4] = 01b).
