ST에서 또 신규 디바이스..

Cortex-M4 에 RGB LCD Interface + SDRAM Interface 을 넣어 놨습니다.

만쉐!!!!!

첨부 Brochure 참고..

• LCD TFT controller

• Up to SVGA format (800x600)

• Up to 24-bit RGB parallel pixel output

• 2‑layer support with blending

• Flexible memory interface with SDRAM support: up to 84 MHz,32‑bit parallel



근데 따로 내부 cache을 가져 가지 않을 텐데 외부 SDRAM속도가 나올려나 모르겠네요.

나중에 UM 나오면 자세히 봐야 겠습니다.


Package도 이쁘게 208LQFP 도 나와 주시공....

UART도 매핑 잘하면 8개까지 사용 하겠네요...


아직 EVK이랑 IC는 풀리지 않았네요...2~3달 기달려야 할 듯




STM32F429BG

High-performance and DSP with FPU, ARM Cortex-M4 MCU with 1 Mbyte Flash, 180 MHz CPU, Art Accelerator, SDRAM, TFT
  • PreviewPreview

The STM32F429xx devices is based on the high-performance ARM®Cortex™-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The Cortex-M4 core with FPU will be referred to as Cortex-M4F throughout this document.

The STM32F429xx devices incorporates high-speed embedded memories (Flash memory up to 2 Mbyte, up to 256 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.

All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers. a true random number generator (RNG). They also feature standard and advanced communication interfaces.
