1 Module introduction
1.1 Type1LV Introduction
WLAN(11a/b/g/n/ac-friendly*1)+BT/BLE(BT5.0) combo SIP module with Cypress CYW43012
The package type is LGA(SM type)
This module is covered with resin molding and fully shielded with metal
MAC and BD address are embedded in OTP
*1: IEEE 802.11ac full-compliance requires support for 40 MHz and 80 MHz channel bandwidths. CYW43012 only
supports 20 MHz channel bandwidth however it supports 802.11ac’s 256-QAM for the 20 MHz channels in the 5GHz
band enabling it to offer higher throughput and lower energy per bit than 802.11n only products.

1.3 Reference Circuit
Figure-2 shows the reference circuit of Type1LV module.
1) Antenna condition for Murata Radio certification
Please add attenuator circuit between Type1LV and antenna matching if you use Murata Radio
certification. If your antenna peak gain is higher than Murata application one, please reduce
antenna gain by this pi-type attenuator.
Please refer to “Type1LV_Antenna_performance.pdf” about more detail.

2) External 32.768kHz Sleep Clock Specifications
Table-1 shows External 32.768 kHz Low-Power Oscillator characteristics for Type1LV.
An external LPO is required.
Parameter External LPO Clock Unit
Nominal input frequency 32.768 kHz
Frequency accuracy +/-250 ppm
Duty cycle 30-70 %
Input signal amplitude 500 – 1800 mVp-p
Signal type Square-wave or sine-wave -
Input impedance*a) > 100k ohm
*a) When power is applied or switch off
3) SDIO
Please arrange SDIO lines with 50ohm and put siries-R, shunt-C parts to reject the noise if needed.
10k~100k ohm pull-ups are required on the four DATA lines and the COMD line. This requirement
must be met duting all operating states by using external pull-ups. This module doesn not have
internal pull-ups on these lines. Please confirm the performance on your board.
4) Guideline for unused pins
All I/O are not needed pull up/down for termination when you don’t use below I/O.

2.2 Antenna
Antenna line should be 50ohm (*). There should be enough GND via along with Antenna line. Make
sure that pi matching circuit is located right before the wifi antenna on the main board.
(*) How to make 50ohm line?
http://www17.plala.or.jp/i-lab/index_e.htm
Here are the conditions of 50ohm lines of evaluation board. (One of example)
Epsilon : 4.3
RF trace width(s) : 0.35mm
GND gap(h) : 0.18mm
GND gap(w) : 0.5mm
The line impedance is Z0 = 51.8ohm.
