SH7285, SH7286

SH7285,SH7286 group are high-end single chip microcontroller incorporating an SH-2A core which realized up to 100MHz operation.


The SH7286 and SH7285 incorporates large capacity Flash memory (SH7286:1MB, SH7285:768KB).

The SH7286 also incorporates register banks. When an interrupt occurs, CPU internal register information is stored in registers at high speed.


This makes it possible to improve real-time control performance greatly. The SH7286 also incorporates various peripheral functions suitable for industrial application AC servos, general-purpose inverters and robots, such as a 1 channel USB2.0 Full Speed, CAN(SH7286 only), 5 channel serial interface, a multifunction timer unit, a 12-bit A/D converter, etc.

 

The SH7286realizes high speed operation of 100MHz, and 5V single power supply or 3.3Vsingle power supply operation. (Analog power supply is 5V)

Hardware Design Support

Title Description
IBIS/BSDL

IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.

BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
