(Meets IEEE 802.11 industrial temperature range)

Application Processor 16-bit, 120 MIPS @ 120 MHz

Serial Interface

UART: Up to 921600 bps, 230400 bps for RS-232.

SPI (slave): Can be clocked up to 20 MHz.

Data Throughput

UART-to-LAN – up to 250 kbps (max) (see

Note 2 and Note 4 below)

LAN-to-UART – up to 203 kbps (max) (see Note 2 and Note 4 below)

Memory

Flash: 64 Kbytes onboard, 512 Kbytes expansion (see Note 3 below)

Connector

36 pin (pn: HRS DF12-36DS-0.5 V) 4-mm height

Note 1: Temperatures above +80°C and below -30°C reduce wireless performance. Module operates from -40°C cold start.

Note 2: Rates are based on operation at maximum wireless data rate, with escape checking set off, serial buffer size set to

maximum, minimum wireless interference, and no other LAN traffic.

Note 3: Flash and SRAM are not available to external applications.

Note 4: WLN UART model only.
