SH7660 Features

This LSI is a RISC (Reduced Instruction Set Computer) microcomputer that integrates a 32-bit

RISC-type SuperH architecture CPU and digital signal processing (DSP) extended function as its

core, together with 16-kbyte cache memory, 16-kbyte X/Y memory, and 128-kbyte U memory, as

well as peripheral functions required for system configuration such as an interrupt controller.

High-speed data transfers can be performed by an on-chip direct memory access controller

(DMAC) and a direct connection to various memories can be performed by the external memory

access support function. Moreover, this LSI also includes powerful peripheral functions that are

essential to system configuration, such as the USB (host/function), high-speed (921 kbits/s)

asynchronous serial interface circuit, voice/audio CODEC serial interface circuit, and D/A

converter.

This LSI also supports the Bluetooth

TM interface as one of peripheral functions and provides the

Bluetooth protocol stack function including firmware up to the HCI layer as a standard function.

Moreover, this LSI has extra processing power to perform the upper protocol stack and various

application profiles to implement the whole Bluetooth baseband functions. The API is also

provided to handle the protocol stack function below the HCI layer so that this Bluetooth interface

can easily be handled like the conventional peripheral functions. This Bluetooth interface can be

connected directly to the RF chip such as the HD157100NP or HD157102NP (manufactured by

Renesas Technology).

Bluetooth is a registered trademark of Bluetooth SIG, Inc., USA. Renesas Technology

uses Bluetooth by entering into licensing agreements.

The features of this LSI are listed in table 1.1.
