Network card platform gains real-time
support
Board support package puts real-time kernel on SH7619 Ethernet-enabled microcontroller development board.
Renesas Technology Europe and Embedded Office have developed a uC/OS-II board support package (BSP) for the M3A-HS19G59 board The board is based on the SH7619 device that features Ethernet MAC and PHY and a 160DMIPS SH2 RISC CPU core, as well as many other peripherals

The H8/38004F MCU offers extremely low power consumption together with 32Kbyte single-supply on-chip Flash memory and is the first in the SLP series that is available in a 64-pin quad flatpack.
The device is comparable in cost to an Ethernet NIC with PHY and so offers the CPU and peripherals "for free", in comparison.
The BSP features the real-time kernel uC/OS-II and the TCP/IP stack uC/TCP-IP.
On top of the TCP/IP stack many application protocols are available, including HTTP, FTP, SNTP, POP, SMTP, DHCP, DNS and more.

The SH7710 32bit RISC microprocessor features an IPsec accelerator for fast encryption and communication processing.
The uC/OS-II real-time kernel is a portable, ROMable, scalable, pre-emptive real-time, multitasking kernel for microprocessors and microcontrollers.
uC/OS-II can manage up to 255 tasks and provides all typical RTOS services like tasks, queues, semaphores, event flags, mailboxes, mutual exclusion semaphores, and more.
The internals of uC/OS-II are described in the book: "MicroC/OS-II, the real-time kernel" which is available worldwide from most technical bookstores.
uC/OS-II is delivered in source code and licensed on a per-product basis and allows you to sell any number of units of the licensed product.
According to Michael Hillmann, Managing Director of Embedded Office: "The high performance of the SH7619 in core and TCP/IP communication opens a wide variety of applications requiring hard real time combined and TCP/IP connectivity".
"The development environment HEW is stable and intuitive usable within a view hours".
"Together with the uC/OS-II BSP this is a great starting point for product development".
"The SH7619 is ideal to replace Ethernet NICs because it is comparable in cost, has a host interface using SRAM-style connection and comes in a very small 13 x 13mm BGA including PHY", says Joachim Hupper, Renesas Technology's Consumer-Industrial Business Unit Marketing Manager.
"Hence it adds intelligence for free and saves board space".
"The new uC/OS-II BSP makes it easy to use the many advantages of the SH7169 and speeds up development".
The SH7619 has a 32bit SH2 RISC CPU core and operates at 125MHz.
It has 16Kbyte cache, 16Kbyte RAM and a bus state controller for SRAM, SDRAM, Flash, PCMCIA etc.
The Ethernet MAC and PHY is supported by a dedicated EDMAC.
The device has a host interface (HIF) that uses a dual-ported SRAM to interface to host CPU as a slave microcontroller, using an SRAM-style interface.
The SH7619 can boot via the HIF so that in slave-mode the use and cost of external Flash can be avoided.
The peripheral set also includes three serial ports, timers and up to 78 I/O ports.
The device comes in a 13 x 13mm RoHS-compliant BGA package with 176 pins and an easy-to-use 0.8mm pitch.
The M3A-HS19G59 board and the SH7619 microcontroller are in mass production and immediately available via all Renesas distributors.
The M3A-HS19G59 board connects to the popular Renesas debugger E10A-lite (HS0005KCU11H), which is also available ex stock.
