68 / 101 page  MPC8314E PowerQUICC II Pro Processor Hardware Specifications, Rev. 2 68 Freescale Semiconductor IPIC This figure provides the AC test load for the GPIO. Figure 53. GPIO AC Test Load 19 IPIC This section describes the DC and AC electrical specifications for the external interrupt pins of the MPC8314E. 19.1 IPIC DC Electrical Characteristics This table provides the DC electrical characteristics for the external interrupt pins. 19.2 IPIC AC Timing Specifications This table provides the IPIC input and output AC timing specifications. 20 SPI This section describes the DC and AC electrical specifications for the SPI of the MPC8314E. Table 60. IPIC DC Electrical Characteristics Characteristic Symbol Condition Min Max Unit Input high voltage VIH — 2.1 NVDD + 0.3 V Input low voltage VIL —–0.3 0.8 V Input current IIN —— ±5 A Output high voltage VOH IOH = –8.0 mA 2.4 — V Output low voltage VOL IOL = 8.0 mA — 0.5 V Output low voltage VOL IOL = 3.2 mA — 0.4 V Table 61. IPIC Input AC Timing Specifications Characteristic Symbol 1 Min Unit IPIC inputs—minimum pulse width tPIWID 20 ns Note: 1. IPIC inputs and outputs are asynchronous to any visible clock. IPIC outputs should be synchronized before use by any external synchronous logic. IPIC inputs are required to be valid for at least tPIWID ns to ensure proper operation when working in edge triggered mode. Output Z0 = 50 NVDD/2 RL = 50 |
