new products UDE supports Freescale MPC5510 32-bit MCU Pls Programmierbare Logik & Systeme announces availability of its Universal Debug Engine (UDE) for Freescale’s MPC5510 Power Architecture 32-bit microcontroller family. The automotive MCUs, with an operating frequency of up to 80 MHz, are – depending on the device type – are provided with: one or two Power e200z cores, up to 1 Mbyte of ﬂash with error correction coding (ECC) and up to 64 kbytes of SRAM. The MPC5510 family of devices – designed speciﬁcally for use in body electronics – provide communication interfaces (FlexRay, MultiCAN, LIN), DMA, low-power mode and additional typical peripheral units such as timer, analog-digital converter, etc. One of the important aspects is the unique modular construction of the UDE, which allows real multi-core debugging within one user interface. This is particularly useful with the dual-core versions of MPC5516 and MPC5514. For example, the four code breakpoints and two watch points per core, which are supported via on-chip hardware, can be used by the developer direct in the program and watch window of the corresponding core. Needless to say, all further on-chip trigger options of the MP5516 are also fully supported by the Universal Debug Engine 2.4 (UDE 2.4). In the process, the debugger allocates programming and also a short turnaround time during development. The existing Nexus unit on all devices of the MPC5510 family enables memory access by the debugger during run-time. For example, this feature can be used for real-time visualization of variables and expressions of them to represent measured values. Furthermore, in this way, a virtual input/output interface is implemented via the JTAG debug channel. The core architectures Power e200z1 and Power e200z0 support VLE, which stands for variable length encoding. This alternative instruction set consists of 16-bit and 32-bit wide instructions and enables a high code density. The Universal Debug Engine provides transparent use of VLE. An additional advantage is the support of the most important compilers. Freescale’s CodeWarrior for MPC55xx devices as well as Wind River’s PowerPC Compiler and the GNU implementation can be used together with pls’ UDE 2.4. www.pls-mc.com the necessary on-chip debug resources automatically. The connection to dual-core devices, such as the MPC5516, typically takes place via a single JTAG interface. In combination with pls’ Universal Access Device 2+ (UAD2+), download rates of up to 1 Mbyte/s can be achieved with the UDE 2.4. This guarantees users of the MPC5510 family a fast FLASH 16-bit MCU is ready to drive dot matirx LCDs Seiko Epson has developed the S1C17702, a 16-bit ﬂash microcontroller that contains a high resolution dot matrix LCD driver, and features low power consumption equivalent to an 8-bit microcontroller. The 16-bit RISC CPU achieves the high-speed processing capability of one clock cycle per instruction. It has a variety of interfaces that enable connection with multiple sensors or peripheral devices. The 128 kbyte onchip ﬂash ROM of the S1C17702 has made it possible to store large volumes of display data, such as programs. 42 The S1C17702, which has a dot matrix LCD driver with a top-ofthe-industry resolution of 72 SEG x 32 COM (2,304 dots), enables direct connection with LCD panels, making the display of such data as Japanese characters or graphs a simple matter. Because the multiple voltages required to drive the LCD panel are generated internally from the power supply voltage, a dedicated power source is not necessary. This product also employs voltage regulator circuit technology, which enables a device to maintain the quality of the display regardless of the charge remaining in the battery. For applications involving displays, which had, up until now, required multiple chips, including dedicated external chips, the S1C17702 has made it possible to construct products with a minimal number of components. The company has made use of the low power consumption technologies accumulated over the years for its watches and other applications to achieve a current consumption, typically 1.0 µA in standby mode. www.epson-electronics.de APRIL 2008 | embedded systems design europe | www.embedded.com/europe 042_ESDE.indd 42 9/04/08 15:29:06 http://www.pls-mc.com http://www.epson-electronics.de http://www.embedded.com/europe
