eZ80AcclaimPlus!™ Wireless Zdots® SBC  
Zilog’s eZ80AcclaimPlus! Wireless Zdots Single Board Computer (SBC) is a compact,  
high-performance board specially designed for the rapid development and deployment of  
embedded systems requiring control and Wireless internet/intranet connectivity.  
This expandable Zdots SBC is powered by Zilog’s latest power-efficient, high-speed,  
optimized pipeline architecture eZ80F91 connectivity ASSP, a member of  
eZ80AcclaimPlus! family.  
eZ80F91 is a high-speed single-cycle instruction-fetch microcontroller, which operates  
with a clock speed of up to 50 MHz.  
The rich-peripheral Wireless Zdots SBC makes it suitable for a variety of applications  
such as Health Care, CE Devices, Energy Management, Smart Appliances, Home Control,  
and Fitness.  
A complete software library is also provided that will include a TCP/IP stack (ZTP),  
including an integrated, preemptive multitasking OS optimized for embedded systems.  
ZTP software suite is optimized to allow development of the low-cost systems. ZTP offers  
full-feature operating system services in addition to network services while occupying  
minimal Program Memory. The applications can be integrated with ZTP via application  
programming interface (API). ZTP is based on Zilog Real-Time Kernel (RZK), which  
includes an embedded file system and support for a wide range of eZ80® peripherals such  
as I2C, SPI, UART, EMAC and RTC.  
The key features of ZTP include:  
•
Compact, preemptive, multitasking, real-time kernel with inter-process communications  
(IPC) support and soft real-time attributes  
•
•
•
Complete TCP/IP stack  
Compatible with all members of the eZ80 family  
Wireless Station Device Mode-Configurable SSID, No Encryption, 64-bit WEP or 128-bit  
WEP Encryption Key support  
•
•
PPoE Client-PPoE Discovery and PPoE Session  
Implementation of the following standard network protocols: ARP, DHCP, DNS, FTP,  
HTTP, SSL, ICMP, IGMP, IP, PPP, RARP, SMTP, TCP, SNMP, UDP, SNTP, Telnet,  
TFTP, and TimeP  
•
•
Interoperable with all RFC-compliant TCP/IP and Network Protocol implementations to  
provide seamless connectivity  
A board support package (BSP) containing an Ethernet Media Access Controller (EMAC)  
driver using the eZ80F91 integrated EMAC

On-Board Component Description  
Power Options for the Real-Time Clock  
An on-board SuperCap C1 (capacitance 0.2 F, Panasonic, part number EEC-EN0F204J1)  
powers the 32 kHz real-time clock when the external power is removed. It is charged  
through diode D1 (ON Semiconductor, part number MMBD101LT1G) when external  
power is applied to the board. The SuperCap C1 is not soldered on the board. You can add  
as an option.  
Memory  
The Wireless Zdots® SBC contains off-chip Flash, SRAM, and on-chip Flash memory and  
SRAM. The off-chip Flash of Zdots SBC has an access time of 70 ns. This access time  
requires four wait states to be added to the cycle when accessing external Flash at 50 MHz  
clock speed. There is up to 1 MB of fast SRAM on the Zdots SBC. Access time is 10 ns,  
which requires an additional one wait-state when accessing it.  
Serial Interface Ports  
The eZ80F91 contains two UARTs with programmable baud rate generators. UART0 is  
connected to J1 and J3. UART1 is connected to J1.  
Do not connect an RS-232 interface without level shifters. There are no  
RS-232 level shifters on the Zdots SBC.

Stresses greater than those listed in Table 6 on page 14 causes permanent damage to the  
device. These ratings are stress ratings only. Operation of the device at any condition out-  
side those indicated in the operational sections of these specifications is not implied.  
Exposure to absolute maximum rating conditions for extended periods may affect device  
reliability. For improved reliability, unused inputs must be tied to one of the supply volt-
