Based on Popular Zilog(R) Serial Communications Controller, New
Solution Is Ideal for Computer Peripherals and Other Applications
Requiring Lower Power SAN JOSE, Calif., June 30
/PRNewswire-FirstCall/ -- Zilog, Inc. (NASDAQ: ZILG) a trusted
supplier of application specific, embedded system-on-chip (SoC)
solutions for industrial and consumer markets, today announced a
new enhanced low-voltage serial communications controller (SCC) for
a variety of computing applications requiring increased performance
and lower power consumption. The Zilog Z8523L Enhanced SCC (ESCC)
builds on Zilog's popular and original discrete SCC, providing a
low-power solution that reduces the voltage from 5 to 3.3 volts.
The ESCC also features performance improvements that allow
applications including computer peripherals, networking equipment
and routers to experience faster data rates and increased processor
bandwidth. "Zilog has made significant improvements with our new
ESCC that helps our customers bring their high-speed data
applications to market quicker, reducing their total cost and
extending the life of their applications," said Mike Orr, Zilog
vice president and general manager, Microcontroller Business Unit.
Before developing the 3.3 volt ESCC, Zilog customers used a
regulator to achieve lower voltage with the original 5 volt Zilog
SCC. The Zilog 3.3 volt ESCC has deeper FIFOs and other features
that significantly reduce the software overhead for each channel.
This allows for more channels per system, faster data rates with
more CPU bandwidth and overall lower CPU costs. The ESCC can
support multiple channel and multiple protocols that easily
interface to 8/16 bit addressable non-multiplexed address/data
buses. The ESCC can be configured to satisfy a wide variety of
serial communications applications. On-chip features include baud
rate generators, digital PLLs and crystal oscillators to reduce
external logic. Additional features may include optimized FIFOs to
support high speed SDLC transfers using DMA controllers. The ESCC
handles asynchronous formats, synchronous byte-oriented protocols
and synchronous bit-oriented protocols. The ESCC can generate and
check CRC codes in any synchronous mode and can be programmed to
check data integrity in various modes. The ESCC also has facilities
for modem controls in both channels. In applications where these
controls are not needed, the modem controls can be used for
general-purpose I/O. Zilog ESCC's are designed for use in multiple
applications for serial communication needs. One of the key
features offered by the ESCC is Extended Read Enable. Write
Register values from the WR3, WR4, WR5, WR7, and WR10 can be
examined in the ESCC. This feature improves system testability. It
is also crucial for SCC/ESCC differentiation and allows generic
software structures for all SCC/ESCC devices. The Zilog Z85230
Enhanced SCC is in production and now available to ship to
customers that place orders through distributors. For more
