5 On-Chip Peripheral Components Semiconductor Group 5 - 1 On-Chip Peripheral Components 5.1 Digital I/O Port Circuitry To realize the Hardware Power Down Mode with floating Port pins in the SAB 80C517A/83C517A 5 the standard port structure used in the 8051 Family is modified (figure 5-1). The FETs p4, p5 and n2 are added. During Hardware Power Down this FETs disconnect the port pins from internal logic. Figure 5-1 Port Structure
Semiconductor Group 5 - 2 On-Chip Peripheral Components P1 and p3 are not active during Hardware Power Down. P1 is activated only for two oscillator periods if a 0-to-1 transition is programmed to the port pin (not possible during HWPD). P3 is turned off during reset state (also HWPD). For detailled description of the port structure please refer to the SAB 80C517/80C537 User’s Manual.
