When exporting the products or technology described herein, you should follow the applicable export control laws and regulations, and procedures required by such laws and regulations.
4. All information included in this document such as product data, diagrams, charts, programs, algorithms, and application circuit examples, is current as of the date this document is issued. Such information, however, is subject to change without any prior notice. Before purchasing or using any Renesas products listed in this document, please confirm the latest product information with a Renesas sales office. Also, please pay regular and careful attention to additional and different information to be disclosed by Renesas such as that disclosed through our website. (http://www.renesas.com )
5. Renesas has used reasonable care in compiling the information included in this document, but Renesas assumes no liability whatsoever for any damages incurred as a result of errors or omissions in the information included in this document.
6. When using or otherwise relying on the information in this document, you should evaluate the information in light of the total system before deciding about the applicability of such information to the intended application. Renesas makes no representations, warranties or guaranties regarding the suitability of its products for any particular application and specifically disclaims any liability arising out of the application and use of the information in this document or Renesas products.
7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below: (1) artificial life support devices or systems (2) surgical implantations (3) healthcare intervention (e.g., excision, administration of medication, etc.) (4) any other purposes that pose a direct threat to human life Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who elect to use Renesas products in any of the foregoing applications shall indemnify and hold harmless Renesas Technology Corp., its affiliated companies and their officers, directors, and employees against any and all damages arising out of such applications.

1.1 Overview

1.1 Overview

The M3A-HS85 is the CPU board designed for users to evaluate the functionalit y and performance of the SH7285 group of Renesas Technology original microcomputer, as well as develop and evaluate the application software for this group of microcomputers. The Sh7285s data bus, address bus and various internal peripheral circuit function pins are connected to the extension connector of the M3A-HS85, al lowing users to evaluate the timing relationship with peripheral devices using measurement instruments or develop extension boards tailored to suit development purposes. Furthermore, the E10A-USB or the on-chip emulator made by Renesas Technology can also be connected to the M3A-HS85.

The SH7285 includes a 768-Kbytes flash memory and 32-Kbytes RAM.

2.3.2 SRAM

Two Mbytes of SRAM can be mounted on the M3A-HS85 (Not mounted). In the M3A-HS85 specification, 3.3V power is supplied to SRAM so that SH7285 should be used in 3.3V when SRAM is mounted (CPU power supply switch jumper (JP1) should be set to “2-3”). SRAM is controlled by the bus state controller built into SH7285. The address spaces of SRAM can be switched to CS0 space, CS2 space, and CS6 space by the pin function controller setting of SH7285.

2.6 Power Supply Module

2.6 Power Supply Module
In M3A-HS85, 5V power is input to the board and 3.3V is generated by using a regulator. The regulator used is
output voltage variable type and given voltage value can be generated by changing the resistance value.
5V power can be supplied from DC stabilized power supply (via power supply connector (J4)) and AC adapter (via
DC power supply jack (J7)).
SH7285 system power supply (VCC) can be switched to 3.3V/5V by setting 3V/5V select jumper (JP1)(Initially it is
set to 5V). When VCC is switched, please note the points shown as follows.
When 5V is set in the state that SRAM or SDRAM is mounted, the voltage that exceeds the maximum rating is
supplied from the address line, data line, and control line to SDRAM or SRAM, and devices could be destroyed. Thus, using like this must be avoided.
(3.3V is supplied to 3V system device such as SRAM and SDRAM even when 5V is set.)
By setting jumpers, system power (VSS), A/D power (AVCC), AVREF power, and USB power (DrVCC) of SH7285
can be individually supplied from external power supply.
Figure 2.6.1 shows the block diagram of M3A-HS85 power supply circuit.

2.7 USB Interface

2.7 USB Interface
The M3A-HS85 contains a USB connector (Standard-B receptacle). When a cable is connected to USB host/hub in the state that this CPU board is not turned on, the voltage is
impressed from USB host/hub to VBUS. Thus, the CPU board should be turned on before USB cable is connected.
When you want to delay a notification of connection to USB host/hub (the cases such as in the processing of high priority or initialization), it can be controlled by PB10. The powered state is kept regardless of the states USD+ and USD- when pin VBUS of SH7285 is set to low level.
