FUNCTIONAL DESCRIPTION
1.1
Overview
The CL-PS7110 is a single-device embedded controller designed to be used in ultra-low-cost applications
such as a hand-held personal organizers and hand-held internet browsers. There are other devices
offered by Cirrus Logic (http://www.cirrus.com) such as fax/modem chipsets, IR chipsets, codecs, etc.,
that can be used around the CL-PS7110 to build a complete hand-held organizer. The CL-PS7110 oper-
ates at both 3 V and 5 V. However, the AC timings shown in this data book (v1.5) reflect 3-V operation.
Figure 1-1
shows a simplified functional block diagram of the CL-PS7110. All external memory and
peripheral devices are connected to the 32-bit data bus, using the external 28-bit address bus and control
signals. Bus transfer times can be extended using the EXPRDY signal to lengthen bus cycles. The max-
imum burst transfer rate of the external bus is approximately 70 Mbytes/sec.
Figure 1-1. Functional Block Diagram
The core-logic functionality is built around an ARM710A microprocessor and 8 Kbytes of cache. At 18.432
MHz (for 3-V operation) and with an on-chip 8-Kbyte cache (four-way set-associative), the CL-PS7110
delivers approximately 15 MIPS of sustained performance (18.4 MIPS peak). This is approximately the
same as a 33-MHz, ’486-based PC.
