1. Introduction
1.1 About this document
This document lists detailed information about the SJA2020 device. It focuses on factual
information like pin information, register views, characteristics etc. Short descriptions are
used to outline the concept of the features and functions. More details and background on
developing applications for this device is given in the SJA2020 User manual (see Ref. 1).
No explicit references are made to the User manual.
Please refer to the SJA2020 Application note ‘Known issues’ (see Ref. 2) for corrections
and additional product information.
1.2 Intended audience
This document is written for engineers evaluating and/or developing systems, hard- and/or
software for the SJA2020. Some basic knowledge of ARM processors and architecture
and ARM7 in particular is assumed (see Ref. 3).
2. General description
2.1 Architectural overview
The SJA2020 consists of an ARM7TDMI-S processor with real-time emulation support,
the AMBA Advanced High-performance Bus (AHB) for interface to the on-chip memory
controllers, a DTL bus (a universal Philips interface) for interface to the interrupt controller
and three VLSI Peripheral Buses (VPB - a compatible superset of ARMs AMBA advanced
peripheral bus) for connection to the on-chip peripherals clustered in so-called
subsystems. The SJA2020 configures the ARM7TDMI-S processor in little endian byte
order. All peripherals run on the same system clock frequency as the ARM7TDMI-S
processor to minimize the access latency time. The AHB2VPB bridge used in the
subsystems contain a write-ahead buffer of 1 deep. This implies that when the ARM7
writes to a register located at the VPB side of the bridge, it will continue even though the
actual write may not yet have taken place. Completion of a second write to the same
subsystem will not be executed until the first write is finished.
2.2 ARM7TDMI-S processor
The ARM7TDMI-S is a general purpose 32-bit processor, which offers high performance
and very low power consumption. The ARM architecture is based on Reduced Instruction
Set Computer (RISC) principles, and the instruction set and related decode mechanism
are much simpler than those of microprogrammed Complex Instruction Set Computers
(CISC). This simplicity results in a high instruction throughput and impressive real-time
interrupt response from a small and cost-effective controller core.
