STMicroelectronics STM32F215ZGT7TR

Overview

STM32F215ZGT7TR from STMicroelectronics is a high-performance ARM® Cortex®-M3 microcontroller featuring 120 MHz CPU operation, 1 MB Flash, 132 KB SRAM (128 + 4 KB), hardware cryptographic acceleration (AES-128/192/256, SHA-1, MD5), and dual USB OTG (FS + HS) with dedicated DMA. It integrates 10/100 Ethernet MAC with IEEE 1588v2 support and an 8–14-bit parallel camera interface-enabling secure industrial gateways and networked vision edge nodes.

For engineers reviewing the STM32F215ZGT7TR datasheet, STM32F215ZGT7TR pinout, STM32F215ZGT7TR application, or STM32F215ZGT7TR equivalent, key selection criteria include its dual-USB-OTG + Ethernet + DCMI combo, crypto engine integration, 144-pin LQFP package with 138 5 V-tolerant I/Os, and ART Accelerator™ enabling zero-wait-state execution from Flash at 120 MHz.

Technical Context

This MCU implements a tightly coupled multi-bus architecture with separate AHB buses for CPU, DMA, and peripherals-enabling concurrent Flash access, Ethernet packet handling, and camera frame capture without bus contention. The ART Accelerator™ uses instruction prefetch and branch prediction to eliminate Flash wait states, while the memory protection unit (MPU) enforces privilege-level isolation between firmware, crypto stack, and network stacks.

The dual USB OTG subsystem includes one full-speed controller with on-chip PHY and one high-speed controller with ULPI interface and dedicated DMA channel; the 10/100 Ethernet MAC supports MII/RMII and hardware timestamping per IEEE 1588v2. The DCMI interface operates up to 48 MB/s with embedded synchronization logic for direct connection to CMOS image sensors.

FAQ

What is the maximum operating temperature rating for STM32F215ZGT7TR?

The STM32F215ZGT7TR is qualified for industrial temperature range: −40 °C to +105 °C. This rating is validated per JEDEC JESD22-A108 and applies to the full LQFP144 package under specified voltage and load conditions. Thermal derating begins above 105 °C ambient, and junction temperature must not exceed 125 °C during operation.

Does STM32F215ZGT7TR support USB HS device mode with an external ULPI PHY?

Yes-STM32F215ZGT7TR's USB OTG HS peripheral supports device, host, and OTG roles using an external ULPI PHY. The ULPI interface operates at 60 MHz and connects via dedicated pins (ULPI_CLK, ULPI_Dx, ULPI_DIR, ULPI_NXT, ULPI_STP). Full-speed mode uses the integrated on-chip PHY and requires no external components.

How many independent 12-bit ADCs does STM32F215ZGT7TR integrate, and what is their maximum aggregate sampling rate?

It integrates three independent 12-bit ADCs (ADC1, ADC2, ADC3), each with up to 24 input channels. In triple interleaved mode, they achieve up to 6 MSPS aggregate sampling rate with synchronized conversion start and shared DMA channel-enabling simultaneous voltage, current, and temperature acquisition in energy metering applications.

Is the 96-bit unique ID accessible via standard debug interface or only through firmware read?

The 96-bit unique ID is readable only via firmware using the DBGMCU_IDCODE register (address 0xE0042000) or HAL_GetUID() API; it is not exposed through SWD/JTAG debug access for security reasons. This prevents unauthorized extraction during board-level debugging or production test, preserving device identity integrity in secure boot and licensing implementations.
