PHYSICAL INTERFACES

ABBTM-NVC-MDCS71

RoHS/RoHS II compliant

19.5 x 12.5 x 2.4 mm SMT

Power Supply

The module integrates internal regulators. It can be easily powered up by connecting a 3V coin battery with a >100uF

capacitor at pin VDD_BAT.

Internal Antenna

The module integrates an on-board chip antenna. There’s no need to use external antenna on customer’s PCB. Please

take precaution to leave ample clearance for the antenna (See Figure 6).

PIO

9 PIOs are provided (4 are multiplexed with SPI debug interface). They are powered from VDD_PIO.

PIO lines are software-configurable as weak pull-up, weak pull-down, strong pull-up or strong pull-down.

AIO

PWM

Figure 2. Capacitor at pin VDD_BAT

Note: At reset all PIO lines are inputs with weak pull-downs. Any of the PIO lines can be configured as interrupt

request lines or as wake-up lines from sleep modes.

3 AIOs are provided. They can be connected to internal 10 bits ADC. Depending on the software, they can be used

to read or output a voltage between 0V to 1.3V. Each of them can be also used as a digital output with special firm-

ware.

PIO3, PIO4, PIO9, PIO10 can be driven by internal PWM module. The PWM module also works while the module

is sleep. Therefore it can be used as a LED flasher. These functions are controlled by special firmwares.

.

UART

This module has a standard UART interface which provides a simple mechanism for communicating with other serial

devices using the RS232 protocol.

The UART CTS and RTS signals can be assigned to any PIO pin by the on-chip firmware.
