The ACM is based on the CC1110 SoC from Texas Instruments. It measures 0.75 by 0.885 inches and is intended for use as a surface-mount module to be soldered on to the PCB of a consumer product. The ACM's energy-aware algorithms support long battery life. When powered by three AA batteries, the ACM by itself can sustain power for over twelve months. The ACM has received regulatory approval for modular devices in the United States (FCC), Canada (IC), and Europe (ETSI). 1.2 Benefits The ACM has been optimized to connect low-cost consumer products to the Arrayent Connect Platform. Benefits include:
Fast time to market 3 ACM Data Sheet - November 7, 2013 - Version 1.3 Revision 3 100% RF-tested in production Low-power consumption: 2.2uA when sleeping, 165uA when operating normally Minimal RF and computer networking experience necessary Easy to implement on a two-layer PCB Supports whole-house coverage (line of sight range: 150 meters, 10 dBm power output) Compliant with ETSI EN 300 328 FCC 15.247a2 / 15.249, IC RSS-201 certified 1.3 Features Features of the ACM include:
2.3V to 5.5V input Three antenna options: external coaxial antenna, wire antenna via through-hole antenna port, and PCB antenna via ACM pin (PCB antenna option will require additional FCC certification testing) Efficient UART interface Operates in unlicensed ISM bands (915 MHz in United States, 868MHz in European Union) 2 Hardware This chapter describes the various hardware requirements and characteristics of the ACM. 2.1 Space Requirements The ACM is designed to be surface-mounted on a carrier board. The ACM requires 0.75 by 0.855 inches of space on your carrier board. 4 ACM Data Sheet - November 7, 2013 - Version 1.3 Revision 3 2.2 Pinout The main interface between the ACM and the Client MCU are the electrical pins of the ACM. If a pin is not noted in the table below, then it should be considered reserved for internal use and should not be connected to the circuit of the carrier board. In the table below, direction is from the perspective of the ACM (input = client MCU ACM ACM, output =
client MCU). Required x Pin #
1-7, 14, 23, 34-
36, 37, Direction Function ACM Ground Description Connected to carrier board ground. Best practice is to connect all pins to ground. At minimum, customer should connect one ground from each corner to 5 Pin #

WAKE_N Bidirectional Active low open collector signal, which is driven low ACM_ENABLE Input ACM_RX ACM_TX Input Output by either the ACM or the client MCU for a preset period of time before sending any data over the UART port. 0 = force awake, 1 = allow sleep. Active low shutdown line which sends the radio link of the ACM into a completely inactive state when driven low. Useful for conserving power. 0 =
disabled, 1 = enabled. UART Rx, for receiving data sent from client MCU. UART Tx, for sending data to client MCU. 6 ACM Data Sheet - November 7, 2013 - Version 1.3 Revision 3 Pin #

When asserted by the Client MCU, the ACM will delay data transmission until the Client MCU releases the signal. Useful in a multi-radio environment for avoiding traffic collisions. 1 = RF busy, 0 = OK for ACM to transmit. Active high output pin which controls the ACM's LED. Active low output pin which forces a hard reboot of the ACM. Input voltage to ACM. 2.3 to 5V DC. Output voltage from ACM. Customers may use VOUT as an external power source for SPI flash. 7 ACM Data Sheet - November 7, 2013 - Version 1.3 Revision 3 2.3 Electrical Characteristics The ACM includes an internal voltage regulator supplied through one of the module pins. Power is sourced from the customer carrier board and must comply with the following characteristics:

Average total when ACM is operating in a normal connected state. laverage is the average value during connected operation assuming that the ACM receives one message every ten minutes. In this state, the ACM is online and is available to send and receive messages in both directions (from the Client MCU to the Arrayent Cloud, and vice versa). 2.4 UART Configuration The following table represents the default UART configuration of the ACM. Parameter Default Value Configurable Baud Rate Data Bits Parity Stop Bits Flow Control Wake Delay 38400. All standard rates from 2400 to 115200 are supported. 8 None 1 None 1. Range of supported values is 1 ms to 255 ms. Yes No No No No Yes Wake Delay refers to the number of milliseconds the ACM will wait after it drives the wake pin low before sending data to the Client MCU. The baud rate of the ACM can be adjusted to meet the needs of your product. 9 ACM Data Sheet - November 7, 2013 - Version 1.3 Revision 3 2.5 Antenna The ACM supports three antenna options:
1. Coaxial external antenna connected to optional U.FL connector 2. Low-cost wire antenna, soldered to the ACM's through-hole antenna port 3. PCB or chip antennas attached to carrier board, connected to RF pin on ACM. Note that this option will require additionall FCC certification testing. Antenna requirements are dictated by the System-on-Chip driving the ACM, the Texas Instruments CC1110. Read more about antenna recommendations for the CC1110 at:
http://www.ti.com/lit/an/swra367a/swra367a.pdf 3 External Flash and SPI - Usage and Requirements The ACM requires access to an external flash memory chip via a shared SPI bus. The shared SPI bus and external flash are used for two purposes:
1. Storing ACM firmware images 2. Storing Client MCU firmware images and data when the ACM performs over-the-air downloads The flash chip must be segmented into a series of contiguous address ranges, called slots. The minimum size for each slot is 64KB. The external flash memory chip must support partial page programming. Compatible models include (but are not limited to):
