2.3 Hardware Design Considerations
2.3.1 Power
The module requires either a 3.3V or 5V supply voltage. There are 2 integrated
on-chip LDOs; VREG and VREGHV. The BCM2070 I/O port is 3.3V tolerant. The
core and RF run at VREG (1.2V). VDDTF is tied to VREGHV which can be
programmed to operate as either a class 1 or a class 2 device.
2.3.2 Clock Sources
A high-accuracy crystal with ±10ppm tolerance is connected to the BCM2070 clock
input pins.
2.3.3 Serial Flash and Firmware Version
Firmware is stored on an onboard serial flash module.
2.3.4 Radio Characteristics
Bluetooth v2.1 + EDR
Frequency Band: 2402 - 2480 GHz
Number of Channels: 79 1MHz channels
