Freescale 16 bit MCU Carle semiconductor upgrade interrupt handling performance

Fly Si Carle (Freescale Semiconductor) semiconductor company's HCS12X series 16 bit microcontroller (MCU) before the date of listing. The device can easily upgrade the existing HCS12 MCU performance to 40MHz. HCS12X can be used for high performance printer, instrument control, industrial intelligent sensing filter (intelligent sensor filtering), automotive applications technology, health care network, wireless communication and central air conditioning ventilation system (HVAC) etc.. HCS12X series built-in XGATE module. This versatile coprocessor is dedicated to handling interrupt events without the need for a central processing unit (PCU). Through the random access memory (RAM) to two times the speed of the CPU clock (80MHz) operation, XGATE can make the CPU does not have to waste resources on time-consuming interrupt processing tasks, and thus focus on processing applications. Therefore, XGATE will help the system to achieve the best real-time processing performance.

Through enhanced CPU with 172 additional instructions, HCS12X series performance can be greatly improved, these additional instructions can be used to improve the encoding efficiency and memory mapping, 32 bit computing function. This series of devices in the pin and code is also highly compatible with the HCS12 series.

Freescale Carle also provides two development platform - DEMO9S12XDT512 and EVB9S12XDP512 for the product designer. The former is a use of MC9S12XDT512 MCU development board demonstrates rapid and simple application development; the latter is a powerful evaluation board, including needed to make full use of the main peripheral MC9S12XDP512 MCU tools.

HCS12XD MCU (CAN bus) in a 112 pin LQFP package, we can supply 10000 pieces of advice, ordering resale price of $10.58 up. HCS12XA (without CAN bus) using the same package, the proposed price of $9.34. DEMO9S12XDT512 demo board priced $75, EVB9S12XDP512 evaluation board priced $395.
