Description The AT45DB641E is a low voltage, low power Serial Flash Device. It boasts 400nA Ultra Deep Power Down currents. The device operates from 1.7V-3.6V and up to 85MHz with a Low Power Read at 15MHz. The AT45DB641E has a flexible erase architecture and can be erased by Page(256bytes), Block(2KB), Sector(64KB), or a full chip erase. The device also offers flexible Writes in which it can be programmed either by Bytes or by Page(256bytes) and has Dual-Input Byte/Page Program capability along with Sequential Program Mode capability. The AT45DB641E offers package options including 8ld SOIC( 0.208” wide) , 9-ball BGA(6x6mm), 44-ball dBGA(3.5x4.2mm), and an 8ld UDFN(5x6x0.6mm) package of which the smMEM-AT45DB641 breakout board makes use of. The smMEM-AT45DB641 provides an easy to use, low-cost, very small breakout board for the AT45DB641. All pins are all mapped to standard 2.54mm/0.1” headers. This allows for use in a standard bread-board or to be ‘wired’ into an application. The header-header spacing is 12.7mm (500mil).

12 Revised 11/2017

Wireless Sensor Prototype The smWSP is a platform that consists of either the smWSP and smRF-CYW2073x-WB and also the Silicon Labs EFM32/EFR32 Starter Kit. There are several combinations in how the boards can be used with or without the other boards. 3 options are outlined below.

1) smSENSR-WSP + smRF-CYW2073x-WB

2) smSENSR-WSP + EFM/EFR32 STK

3) smRF-CYW2073x-WB(standalone BTLE evaluation board)

13 Revised 11/2017

smWSP The smWSP (Wireless Sensor Prototype) is a board that allows the Sensor Maestros smSENSR, smMEM, smCOM, smBAT products to be plugged into the WSP allowing Rapid Prototyping of a Sensor/Wireless Sensor system. On the right hand side it can be directly connected to the smRF-CYW2073x-WB to add BTLE capability and on the Left-hand side it can directly connect to ANY of the Silicon Labs EFM32/EFR32 Starter kits to add a high performance/ultra-low power MCU capability to a system. The WSP has been designed with a Slide Switch to accommodate the slight variations of the EFM32 Starter Kits. The smWSP can be used with the smRF-CYW2073x-WB or with the EFM32 Starter Kits OR with both.

Features • Allows use of all Sensor Maestros smSENSR, smMEM, smCOM, smBAT Products

o I2C and SPI slots available • Direct Connection to smRF-CYW2073x-WB, for easy programming/debugging of BTLE plugins. • Direct Connection with all Silicon Labs EFM/EFR32 Starter Kits • 2 COM-FT230/USB-UART slots • Selectable Voltage between: VMCU(EFM32 Starter Kits), 3V3(from EMCOM-FT230), or from Regulated

voltage supplied by smRF-CYW2073x-WB (typically when the smRF-CYW2073x-WB is powered from a battery and uses the DC/DC converter to provide regulated voltage to the BTLE module.

• Allows for UART, LPUART, and SPI serial communication from the EFM32 Starter kits to the smRF-CYW2073x-WB. Selectable with Slide Switches and DIP switch selectors.

• Several GPIO can be directly connected between EFM32 STK’s and smRF-CYW2073x-WB • GPIO pins can individually be connected to Sensor INT lines for individual Interrupt control

smRF-CYW2073x-WB

The smRF-2073x-WB(Wireless Base) provides a means to plug in BTLE module carrier boards. It also has a connector that allows the emBAT products to be plugged into the kit. The smRF-CYW2073x-WB can be used as a Standalone Eval/prototype board OR can be connected to the smWSP which allows it to be programmed by the smCOM-FT230 and allows it to connect to any of the smSENSR, smMEM, smCOM products for rapid prototyping. There are 2 smCOM-FT230 slots on the smSENSR-WSP so one may be dedicated to UART Programming/Bootload while the other is used for debug output. With the smWSP connected to the smRF-CYW2073x-WB it also allows the user to connect to any of the Silicon Labs EFM/EFR32 Starter Kits and allows for SPI and UART COMs to the EFM32 Starter Kits and allows for several GPIO’s to be directly connected to the EFM32 Starter Kit. The following carrier boards that plug directly into the WSP are the following… smRF-CYW20736S-C: Broadcom BCM20736S based. smRF-CYW20737S-C: Broadcom BCM20737S based.

Features • Pluggable Wireless Socket. Allows for multiple options for wireless connection. • Direct connection to smWSP for Rapid Sensor development and easy programming/debugging of the

BTLE modules. • smBAT battery READY for multiple Battery Options. • Small but useable size with easy probing of all BTLE pins.

smWSP-ARD The smWSP-ARD is the second offering for the Sensor Maestros Wireless Sensor Prototype platform that is in the form of an Arduino Shield. The smWSP-ARD provides the same functionality as the sm-WSP but in a Arduino Shield Compatible format.

Features • Allows use of all Sensor Maestros smSENSR, smMEM, smCOM, smBAT, smPWR Products

o I2C and SPI smBLOCKS available • Arduino Shield compatible. • Pin Compatible with the Nordic nRF52 DK. • 1 smCOM-FT230/USB-UART slot • Selectable Power Supply

o 3.3V from Arduino Base o LiPo with DC/DC, such as smPWR-MP2148 o smBAT Connector o External Power Supply

• Allows configurable SPI and GPIO Interrupt lines from smRF-WB2 to I2C and SPI smBLOCKS for Sensor and Memory products. Selectable with slide switches and DIP switch selectors.

• 4 I2C, 1 SPI, smBLOCKS • 1 smBAT, 1 smPWR, 1 smCOM BLOCKS • 1 LiPo connector • Can be programmed directly with the Nordic nRF52 DK(if plugged in as a shield into the nRF52 DK) • 10pin SWD Connector for use with external SWD Programmer/Debugger(for external
