The N588H340 is an advanced 3-ch Voice/Melody IC that combines with the technology of 8-bit 65C02 core and new 4-bit or 5-bit MDPCM synthesizer to implement sophisticated applications in high level of sound quality.

The N588H340 improves the structure to minimize the external components for various applications. In addition, it allows customers to use internal Rosc with precise frequency control to save BOM cost and gain lower frequency deviation.

Furthermore, the N588H340 provides lots of function includes 24 I/Os where one port with high drive current, 192 bytes RAM, H/W IR carrier, 2-ch Comparator and Low Voltage Detection. Meanwhile, N588H340 builds in 3-pair output pins with 64-level control for the applications of motors tiny control. The N588H340 also build in Watch Dog Timer and Low Voltage Reset to prevent latch-up situation occurring.
