Overview
Features
This LSI is a single-chip RISC microprocessor that integrates a 32-bit RISC-
type Super H architecture CPU with a digital signal processing (DSP) extension
as its core, together with a large-capacity 32-kbyte cache memory, a 16-kbyte
X/Y memory, and an interrupt controller. High-speed data transfers can be
performed by an on-chip direct memory access controller (DMAC), and an
external memory access support function enables direct connection to different
kinds of memory. This LSI also supports a stereo audio recording and playback
function, a USB host controller, a function controller, an LCD controller, a
PCMCIA interface, an A/D converter, and a D/A converter.
The USB host controller and LCD controller have bus master functions, so that
data supplied from an external memory (area 3) can be freely processed. Since
the USB host controller, in particular, conforms to Open HCI standards, it is
extremely easy to transfer data from the PC of a device driver or other
devices. Also, low-power operation suitable for battery operation is possible
because the LCD controller continues to display even in sleep mode.
A powerful built-in power management function keeps power consumption low,
even during high speed operation. This LSI is ideal for electronics devices,
which require both high speed and low power consumption.
The SH7720 group integrates an SSL (Secure Socket Layer) accelerator that
performs RSA (Rivest-Shamir-Adleman) operations and DES (Data Encryption
Standard) and Triple-DES encryption/decryption, while the SH7721 group does
not have the SSL accelerator. Each group consists of several models which
includes or does not include an SD host interface (SDHI) to be suited to a
variety of applications. See table 1.2 and 1.3, Product Lineup, for the models
including (or not including) the SDHI.
