Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TMS5701227CPGEQQ1 16/32-bit RISC Flash microcontrollers (MCUs) are a family of high-performance automotive-grade microcontrollers for safety systems. It features a safety architecture that includes dual CPUs in lockstep, CPU and memory built-in self-test (BIST) logic, ECC on Flash and data SRAM, parity on peripheral memories, and loop functions on peripheral I/O. The TMS570LS1227 device integrates an ARM Cortex-R4F floating-point CPU and has a configuration that can run up to 180MHz providing up to 298 DMIPS. The device supports word invariant high priority [BE32] format.

The TMS5701227CPGEQQ1 features 1.25MB of integrated Flash and 192KB of data RAM with single-bit error correction and double-bit error detection. The device's flash memory is a non-volatile, electrically erasable programmable memory. It is implemented through a 64-bit wide data bus interface. For all read, program, and erase operations, the flash operates at a 3.3V supply input (the same level as the I/O supply). In pipeline mode, the Flash memory is clocked at a system frequency of up to 180 MHz. the SRAM supports single-cycle read and write accesses in single-byte, half-word, single-word, and double-word modes over the full range of supported frequencies.

The TMS5701227CPGEQQ1 features peripherals for real-time control applications, including two Next Generation High-End Timer (N2 HET) timing co-processors, up to 44 I/O terminals, seven Enhanced Quadrature Encoder Pulse (ePWM) modules with up to 14 outputs, six Enhanced Capture (eCAP) modules, two Enhanced Quadrature Encoder Pulse ( eQEP) modules, and two 12-bit analogue-to-digital converters (ADCs) supporting up to 24 inputs.

With integrated safety features and a variety of communication and control peripherals, the Texas Instruments TMS5701227CPGEQQ1 is an ideal solution for high-performance real-time control applications with safety-critical requirements.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
