CPU and On-Chip Memory

• ESP32-C5 embedded, 32-bit RISC-V

single-core microprocessor, up to 240 MHz

• ROM: 320 KB

• HP SRAM: 384 KB

• LP SRAM: 16 KB

• SPI flash: 4 MB

Wi-Fi

• 1T1R in 2.4 and 5 GHz dual band

• Operating frequency: 2412 ~ 2484 MHz, 5180 ~

5885 MHz

• Data rate up to 150 Mbps

• IEEE 802.11ax-compliant

– 20 MHz-only non-AP mode

– Uplink and downlink OFDMA to enhance

connectivity and performance in

congested environments for IoT

applications

– Downlink MU-MIMO (multi-user, multiple

input, multiple output) to increase network

capacity

– Beamformee that improves signal quality

– Spatial reuse to maximize parallel

transmissions

– Target wake time (TWT) that optimizes

power saving mechanisms

• IEEE 802.11ac-compliant

– 20 MHz bandwidth

– Downlink fullband MU-MIMO

• Fully compatible with IEEE 802.11b/g/n protocol

– 20 MHz and 40 MHz bandwidth

– MCS0 ~ MCS7

– Wi-Fi Multimedia (WMM)

– TX/RX A-MPDU, TX/RX A-MSDU

– Immediate Block ACK

– Fragmentation and defragmentation

– Transmit opportunity (TXOP)

– Automatic Beacon monitoring (hardware

TSF)

– Four virtual Wi-Fi interfaces

– Simultaneous support for Infrastructure

BSS in Station mode, SoftAP mode, Station

+ SoftAP mode, and promiscuous mode

Note that when ESP32-C5 scans in Station

mode, the SoftAP channel will change

along with the Station channel

– Antenna diversity
