2. Product Description
The BTM2CS1010A Module is a CSR μEnergy platform device. CSR μEnergy are CSR's single-mode Bluetooth low energy products for the Bluetooth Smart market. BTM2CS1010A Module increases application code and data space for greater application development flexibility.
CSR μEnergy enables ultra low-power connectivity and basic data transfer for applications previously limited by the power consumption, size constraints and complexity of other wireless standards. BTM2CS1010A Module provides everything required to create a Bluetooth low energy product with RF, baseband, MCU, qualified Bluetooth v4.1 specification stack and customer application running on a single IC.
3. Applications
iPhone, iPad, iPod and Mac products and leading Android devices. Bluetooth low energy takes less time to make a connection than conventional Bluetooth wireless technology and can consume approximately 1/20th of the power of Bluetooth Basic Rate. BTM2CS1010A QFN supports profiles for health and fitness sensors, watches, keyboards, mice and remote controls. Typical Bluetooth Smart applications:
HID: keyboards, mice, touch pads, remote controls
Sports and fitness sensors: heart rate, runner speed and cadence, cycle speed and cadence
Health sensors: blood pressure, thermometer and glucose meters
Mobile accessories: watches, proximity tags, alert tags and camera controls
Smart home: heating control and lighting control

6.2 RECOMMENDED OPERATING CONDITIONS 
BTM2CS1010A is reliable and qualified to 4.3V (idle, active and deep sleep modes) and 3.8V (all modes), but there are minor deviations in performance relative to published performance values for 1.8V to 3.6V. For layout guidelines for 4.3V operation, see CSR1000 Hardware Design Review Template.
(b) Safe to 4.3V if VDD_BAT = 4.3V.

7. Circuit Description
System RAM
64KB of integrated RAM supports the RISC MCU and is shared between the ring buffers used to hold data for each active connection, general-purpose memory required by the Bluetooth stack and the user application .
Internal ROM
BTM2CS1010A QFN has 64KB of internal ROM. This memory is provided for system firmware implementation. If the internal ROM holds valid program code, on boot-up, this is copied into the program RAM.
Microcontroller
The MCU, interrupt controller and event timer run the Bluetooth software stack and control the Bluetooth radio and external interfaces. A 16-bit RISC microcontroller is used for low power consumption and efficient use of memory.
Programmable I/O Ports, PIO and AIO
12 lines of programmable bidirectional I/O are provided. They are all powered from VDD_PADS. PIO lines are software-configurable as weak pull-up, weak pull-down, strong pull-up or strong pull-down. 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 to wake the IC from deep sleep mode.
Programming and Debug Interface
Important Note:
The BTM2CS1010A module debug SPI interface is available in SPI slave mode to enable an external MCU to program and control the BTM2CS1010A QFN, generally via libraries or tools supplied by CSR. The protocol of this interface is proprietary. The 4 SPI debug lines directly support this function.
The SPI programs, configures and debugs the BTM2CS1010A QFN. It is required in production.
 

Ensure the 4 SPI signals are brought out to either test points or a header.

Take SPI_PIO#_SEL high to enable the SPI debug feature on PIO[8:5].

Reset

BTM2CS1010A QFN is reset by:

Power-on reset

Software-configured watchdog timer

 

8. Solder Profiles

Composition of the solder ball: Sn 95.5%, Ag 4.0%, Cu 0.5%

 

Typical Lead-Free Re-flow Solder Profile

Key features of the profile:

l Initial Ramp = 1-2.5°C/sec to 175°C±25°C equilibrium

l Equilibrium time = 60 to 180 seconds

l Ramp to Maximum temperature (250°C) = 3°C/sec max.

l Time above liquidus temperature (217°C): 45-90 seconds

l Device absolute maximum reflow temperature: 260°C

 

Devices will withstand the specified profile. Lead-free devices will withstand up to three reflows to a maximum temperature of 260°C.

Notes:They need to be baked prior to mounting.
