| Origin | Original Factory |
Product Overview
Z8523016VEG is Zilog’s dual-channel ESCC, pin-to-pin upgraded from Z8030/Z8530 SCC. It runs at 16MHz, supports asynchronous, Bisync, HDLC/SDLC protocols, and features 4-byte TX / 8-byte RX FIFO per channel to cut CPU interrupt load. Made with CMOS process for low power, this 44-PLCC chip fits telecom, industrial and avionic serial communication equipment.
Core Advantages
Optimized FIFO Storage Blocks
4-byte transmit FIFO & 8-byte receive FIFO on dual channels, lower CPU interrupt pressure and avoid communication errors.
Flexible Multi-Protocol Execution
Compatible with asynchronous, Monosync, Bisync, SDLC and HDLC for various industrial network designs, supports built-in CRC verification.
Enhanced Baud Rate Generators
Dual independent programmable BRGs per channel for accurate, adjustable baud rates.
Robust PLCC Surface-Mount Housing
44-pin PLCC with J-bend leads, anti-vibration and stable contact for harsh temperature environments.
Dedicated Modem Control Pins
Integrated modem I/O pins, configurable as general-purpose GPIO for flexible peripheral expansion.

Frequently Asked Questions
Q1: What does VEG suffix stand for on Z8523016VEG?
A: V=44-PLCC package; E=-40~+85°C industrial temp range; G=RoHS lead-free green device.
Q2: What upgrades does Z85230 have over Z8530?
A: Expanded FIFO (4-byte TX /8-byte RX), improved hardware flow control and baud rate generators, less CPU load during high-speed transmission.
Q3: Can Z8523016VEG work with PLCC sockets?
A: Yes. Its 44-PLCC package supports socket plug-in for debugging, or direct SMT soldering for mass production.
Q4: PCB layout tips for stable high-speed serial signal?
A: Place 0.1μF bypass capacitor near Vcc pin; route differential serial traces above complete ground plane; keep clock traces short and isolated from noisy digital circuits.
Q5: Is this chip compatible with 3.3V power supply?
A: No, the standard operating supply voltage is 5V ±10%, 3.3V power cannot drive this controller normally.
Q6: Can multiple Z85230 chips run on the same host bus?
A: Yes, you can add address decoding logic to mount several ESCC controllers on one microprocessor bus for multi-channel serial expansion.
Q7: What is the maximum serial baud rate supported?
A: The chip supports a maximum data transfer rate up to 0.512 Mbps under 16MHz clock input.
Q8: Does Z8523016VEG support CRC error detection?
A: Yes, built-in CRC verification function specially designed for SDLC/HDLC communication transmission.
