DS5001FP PIN DESCRIPTION PIN 80 PIN 44 PIN 11, 9, 7, 31 5, 1, 79, (P0.5) 77, 75 15, 17, 19, 21, 44 25, 27, (P1.3) 29, 31 49, 50, 51, 56, — 58, 60, 64, 66 NAME FUNCTION P0.0– P0.7 General-Purpose I/O Port 0. This port is open-drain and cannot drive a logic 1. It requires external pullups. Port 0 is also the multiplexed expanded address/data bus. When used in this mode, it does not require pullups. P1.0– P1.7 General-Purpose I/O Port 1 P2.0– P2.7 General-Purpose I/O Port 2.
DS5001FP PIN DESCRIPTION (continued) PIN 80 PIN 44 PIN 53, 16, 41, 36, 8, 18, 42, 32, 80, 76, 30, 34, 4, 6, 20, 35, 43, 24, 26, 1, 2, 3, 28, 30, 4, 5, 7, 33, 35, 9 37 71, 69, 28, 26, 67, 65, 24, 23, 61, 59, 21, 20, 57, 55 19, 18 NAME FUNCTION BA14– BA0 Byte-Wide Address Bus Bits 14–0. This bus is combined with the nonmultiplexed data bus (BD7–0) to access NV SRAM. Decoding is performed using CE1 through CE4 . Therefore, BA15 is not actually needed. Read/write access is controlled by R/ W .
DS5001FP PIN DESCRIPTION (continued) PIN 80 PIN 44 PIN NAME 42 — VRST 43 — PF 14 40 MSEL 73 — N.C. FUNCTION This I/O pin (open drain with internal pullup) indicates that the power supply (VCC) has fallen below the VCCmin level and the micro is in a reset state. When this occurs, the DS5001FP drives this pin to a logic 0. Because the micro is lithiumbacked, this signal is guaranteed even when VCC = 0V. Because it is an I/O pin, it also forces a reset if pulled low externally.

DS5001FP Figure 5 illustrates a typical memory connection for a system using a 128kB SRAM. Note that in this configuration, both program and data are stored in a common RAM chip Figure 6 shows a similar system with using two 32kB SRAMs. The byte-wide address bus connects to the SRAM address lines. The bidirectional byte-wide data bus connects the data I/O lines of the SRAM. Figure 5.
DS5001FP Figure 6. DS5001FP CONNECTION TO 64k x 8 SRAM POWER MANAGEMENT The DS5001FP monitors VCC to provide power-fail reset, early warning power-fail interrupt, and switch over to lithium backup. It uses an internal bandgap reference in determining the switch points. These are called VPFW, VCCMIN, and VLI, respectively. When VCC drops below VPFW, the DS5001FP performs an interrupt vector to location 2Bh if the power-fail warning was enabled. Full processor operation continues regardless.
