Solution Highlights

•

A complete Wi-Fi subsystem that complies

with IEEE 802.11b/g/n protocol and supports

Station, SoftAP, and SoftAP + Station modes

•

A Bluetooth LE subsystem that supports

features of Bluetooth 5 and Bluetooth mesh

•

Xtensa® 32-bit LX7 dual-core processor with a

five-stage pipeline that operates at up to 240

MHz

– A 128-bit data bus and dedicated SIMD

instructions to provide high computing

performance

– Efficient L1 cache to improve execution of

external memory

– Single-precision floating-point unit (FPU) to

accelerate computing

•

Highly-integrated RF module that provides

industry-leading power and RF performance

•

State-of-the-art power management designed

for a wide range of applications with its multiple

low-power modes. The ULP coprocessor can

operate in ultra-low-power mode.

•

Powerful storage capacities ensured by 512

KB SRAM and 384 KB ROM on the chip, and

SPI, Dual SPI, Quad SPI, Octal SPI, QPI, and OPI

interfaces that allow connection to flash and

external RAM

•

Reliable security features ensured by

– Cryptographic hardware accelerators that

support AES-128/256, Hash, RSA, HMAC,

digital signature, and secure boot

– Random number generator

– Permission control on accessing internal

and external memory

– External memory encryption and decryption

•

Rich set of peripheral interfaces and GPIOs,

ideal for various scenarios and complex

applications
