St MicroElectronics ARM Cortex-M4 Microcontroller 168 MHz 1 MB Flash LQFP-100

St MicroElectronics ARM Cortex-M4 Microcontroller 168 MHz is a high-performance 32-bit microcontroller based on the ARM Cortex-M4 RISC core, capable of operating at frequencies up to 168 MHz.

The core includes a Floating-Point Unit (FPU) for single-precision arithmetic, supporting all ARM single-precision data processing instructions, along with a comprehensive set of Digital Signal Processing (DSP) instructions. This makes the device well suited to computationally intensive applications. An integrated Memory Protection Unit (MPU) is also included to enhance application security.

The device provides up to 1 MB of Flash memory and up to 192 KB of SRAM, plus an additional 4 KB of backup SRAM. Its peripherals and I/Os are organised across two APB buses, three AHB buses, and a 32-bit multi-AHB bus matrix.

Key Features

• High-Performance Core: ARM Cortex-M4 with FPU and DSP instructions
• Memory Interface: Flexible static memory controller supporting Compact Flash, SRAM, PSRAM, NOR, and NAND memories, plus an LCD parallel interface (8080/6800 modes)
• Clock Management: 4 MHz to 26 MHz crystal oscillator, internal 16 MHz RC oscillator (1% accuracy), and 32 kHz oscillators for RTC with calibration
• Power Modes: Low-power Sleep, Stop, and Standby modes, with a dedicated VBAT supply for RTC and backup registers
• Analogue Capabilities: Three 12-bit, 2.4 MSPS Analogue-to-Digital Converters (ADCs) and two 12-bit Digital-to-Analogue Converters (DACs)
• Connectivity: Up to 3x I2C (SMBus/PMBus), up to 3x SPI, 2x CAN (2.0B Active), SDIO, and a USB 2.0 full-speed device/host/OTG controller with on-chip PHY
• I/O Flexibility: Up to 140 I/O ports with interrupt capability, 136 fast I/Os (up to 84 MHz), and 138 5V tolerant I/Os
