Zilog, a provider of embedded system-on-chip (SoC) devices, has introduced Z8523L Enhanced SCC (ESCC), a new serial communications controller (SCC) for a variety of computing applications. The new ESCC builds on Zilog’s SCC, providing a low-power device that is expected to reduce the voltage from 5 to 3.3 volts.
Zilog said that the ESCC can support multiple channel and multiple protocols that interface to 8/16 bit addressable non-multiplexed address/data buses. The ESCC can be configured to suit an array of serial communications applications.
On-chip features include baud rate generators, digital PLLs and crystal oscillators to reduce external logic. Additional features may include optimised FIFOs to support SDLC transfers using DMA controllers.
The company claims that 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.
According to the company, the ESCCs are designed for use in multiple applications for serial communication needs. One of the 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 featureis claimed to enhance system testability.
