Description

The OB36A01A1 microcontroller uses an advanced RISC core architecture. OB36A01A1 features an enhanced kernel, a four-level stack, and multiple internal and external interrupt sources.

The independent instruction and data bus allows for 14-bit wide instruction words and independent 8-bit wide data.
