Z8523016VEG – Enhanced Serial Communications Controller (ESCC) with Dual-Channel Interface
The Z8523016VEG is a high-performance 5V CMOS serial communications controller from Zilog, designed for robust data transmission in industrial and embedded systems. This IC features dual full-duplex channels, supporting multiple communication protocols including HDLC, SDLC, BISYNC, and asynchronous/synchronous modes, with a maximum data rate of 0.512 Mbps per channel. Encased in a 44-pin PLCC (J-Lead) package, it operates across an industrial temperature range (-40°C to +100°C) and integrates advanced functionalities like DMA control, FIFO buffering (10-byte Rx/Tx), and modem I/O lines configurable as general-purpose I/Os. Its 16.384 MHz clock frequency and 4.5V–5.5V supply range make it ideal for legacy telecom, industrial automation, and networking equipment requiring reliable serial communication.
Key Features & Benefits
The Z8523016VEG stands out with its protocol flexibility, supporting NRZ, NRZI, FM0/FM1 (biphase), and Manchester encoding. Its low power consumption (7mA typical) and ±15mA driver output current ensure efficient operation in power-sensitive designs. The controller includes error detection (CRC, parity), Z-Bus compatibility, and integrated DMA support for high-throughput data transfer. The 44-PLCC surface-mount package (16.585mm × 16.585mm) ensures compact PCB integration, while RoHS compliance aligns with modern environmental standards. Applications span POS terminals, legacy telecom switches, and industrial control systems.
Application
This controller is widely used in industrial automation (PLC communication), legacy telecom infrastructure (modems, routers), and embedded systems requiring multi-protocol serial interfaces. Its noise-immune differential signaling and FIFO buffering make it suitable for long-distance data links, while its DMA capability optimizes CPU utilization in Z80/Z8-based systems.
