3.2 Power Manager Unit PM8916 introduction
The PM8916 device integrates all wireless handset power management, general housekeeping, and user interface support functions into a single mixed-signal IC. The versatile design is suitable for multimode, multiband phones and other wireless products such as data cards and PDAs. The PM8916 mixed-signal HV-CMOS device is available in the 176-pin nanoscale package (NSP) that includes several ground pins for improved electrical ground, mechanical stability, and thermal continuity. Since the PM8916 device includes so many diverse functions, its operation can be understood better by studying the major functional blocks individually. Therefore, the PM8916 document set is organized by the device functionality as follows:
Input power management Output power management General housekeeping User interfaces IC interfaces
– either multipurpose pins (MPPs) or general-purpose input/output
(GPIOs) – that can be configured to function within some of the other categories.

3.3 RF Chip WCN3620 device introduction
The WCN3620 IC integrates three different wireless connectivity technologies into a single device suitable for handsets and other mobile devices: Wireless local area network (WLAN) compliant with the IEEE 802.11 b/g/n
specification
Bluetooth (BT) compliant with the BT specification version 4.0 (BR/EDR+BLE) Worldwide FM radio, with Rx modes supporting the Radio Data System (RDS) for
Europe and the Radio Broadcast Data System (RBDS) for the USA The WCN3620 is a highly integrated IC using the 3.32 × 3.55 × 0.63 mm, 61-pin wafer-level nanoscale package (61 WLNSP) – and is supplemented by modem IC processing (such as the MSM8x26 IC, a device in the MSM™ chipset family) to create a wireless connectivity solution that reduces the part count and PCB area. The WCN3620 IC ensures hardware and software compatibility with companion Qualcomm Atheros (QCA) chipsets to simplify the design cycle and reduce the OEM time-to-market cycle. The WCN3620 IC uses low-power 65 nm RF CMOS fabrication technology, making it perfectly suited for battery-operated devices where power consumption and performance are critical.
The WCN3620 device’s major functional blocks are:
A single-band WLAN RF BT radio (RF and digital processing) FM radio (RF and digital processing) Shared WLAN + BT RF front-end (RF FE) circuits Top-level support circuits that interface with the modem IC, buffer the XO input,
generate the wireless connectivity network (WCN) internal clocks, and gate and
distribute DC power to the other blocks
New features introduced into the WCN3620 IC
65 nm RF CMOS technology in the small 61 WLNSP Highly integrated front-end eliminates external PA and LNA matching, and antenna
Tx/Rx switching.
Support for ANT Support for the IEEE802.11b/g/n standard Single-band WLAN: 2.4 GHz RF transceivers Compliant with BT specification version 4.0 Concurrent WLAN + BT reception in the 2.4 GHz band Lower power consumption Smaller IC footprint, lower parts count, and less PCB area overall
