2.2.1 SH7619

The M3A-HS19 CPU board includes the SH7619, the 32-bit RISC MCU operates with a maximum frequency of 125 MHz.
The SH7619 is equipped with an Ethernet controller that includes an IEEE802.3u compliant Media Access Controller and
a Physical Layer Transceiver. Moreover, the SH7619 has both a 16-KB U memory (RAM) and a 16-KB instruction/data
unified cache memory. These on-chip modules enable the SH7619 to be used in a wide range of applications from data
processing to control equipments.
The M3A-HS19 can be operated at a maximum frequency of 125 MHz (external bus: 62.5 MHz, max) using a 15.625 MHz
input clock. The dedicated clock of 25.000 MHz input from CK_PHY pin is used as an on-chip PHY clock.
Figure 2.2.1 shows the SH7619 pin assignments.
