The N588HP340 is an OTP solution for the N588Hxxx family. It 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 N588HP340 improves the structure to minimize the external components for various application circuits. In addition, it allows customers to use internal Rosc with precise central frequency control to save BOM cost and get lower frequency deviation.

The N588HP340 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 4 levels voltage detection. Meanwhile, N588HP340 builds in 3-pair output pins with 64-level control for the application of motor control or LED fading effect. The N588HP340 also provides Watch Dog Timer and Low Voltage Reset to prevent latch-up situation occurring.
