AR4100 Datasheet, PDF (8/29 Pages) Freescale Semiconductor, Inc – Low power modes consuming as little as 5 μA of current

AR4100 System in Package 802.11n– General Availability Data Sheet
Features Summary
2.4 Manufacturing Calibration
The AR4100 uses internal self-calibration and BIST (built-in self test) circuits to maintain optimal
performance over temperature, time and process variation. The AR4100 is delivered fully tested
and does not require any customer manufacturing line calibration.
2.5 Internal One-Time Programmable Memory
The AR4100 includes internal one-time programmable memory which is used to store the device
MAC address. This OTP memory must be programmed during the customer manufacturing flow
with a MAC address. Tools and application notes are provided to enable customers to integrate this
into their manufacturing flow.
om _{2.6 Reference Frequency}
.c ^{The AR4100 incorporates an integrated 26 MHz crystal.}
le 2.7 Internal Sleep Clock
a The AR4100 incorporates integrated on-chip low power sleep clocks to regulate internal timing,
eliminating the need for any external 32 KHz real time clocks or crystal oscillators.
sc _{2.8 Interfaces}
e _{The AR4100 supports a variety of interfaces for supporting host interface options, and external}
memory interface options.
.fre 2.8.1 Standard Host Interface
The AR4100 supports a generic SPI (GSPI) slave port when interfacing to a host MCU.
w _{2.8.2 Firmware Loading and Other Interfaces}
w GSPI master for interfacing to an external NVMEM for firmware load into the AR4100 upon
w^powerup.
