On-chip memory: 2 MB of Flash for secure firmware and credential storage, plus 170 KB of SRAM — enough headroom for the application stack, a TLS handshake buffer, and the RTOS footprint without external memory. The MAX32520-BNS+ belongs to the DeepCover series, Analog Devices' security-focused MCU family. These parts integrate tamper detection, secure key storage, and encrypted memory access — the peripheral set (DMA, PWM, WDT) supports real-time monitoring and watchdog-based tamper response. The 27 I/O lines connect to keypad matrices, secure accessory authentication interfaces, or tamper-switch inputs. ## 32-TQFN footprint — board-fit note Surface-mount assembly with an internal oscillator — no external crystal required for the core clock, though the UART/USART baud-rate accuracy depends on the internal RC tolerance.","metaTitle":"MAX32520-BNS+ Analog Devices MCU, 120MHz ARM Cortex-M4F","metaDescription":"MAX32520-BNS+ DeepCover secure MCU: 120MHz ARM Cortex-M4F, 2MB Flash, 170KB RAM, 32-TQFN.
