N588H061 Datasheet | Nuvoton Technology

Description The N588Hxxx is an advanced 3-ch Voice/Melody IC that bines with the technology of 8bit 65C02 core and new 4-bit or 5-bit MDPCM synthesizer to implement sophisticated applications in high level of sound quality. The N588Hxxx improves the structure to minimize the external ponents 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 N588Hxxx provides lots of function includes 16 ~ 24 I/Os where one port with high drive current, 128 ~ 192 Bytes RAM, H/W IR carrier, 2-ch parator and Low Voltage Detection. Meanwhile, N588Hxxx builds in 3-pair output pins with 64-level control for the applications of motors tiny control. The N588Hxxx also build in Watch Dog Timer and Low Voltage Reset to prevent latch-up situation occurring. The N588Hxxx family contains several items with different playback ROM size and duration as shown below table: N588Hxxx ROM (KB) Sec.
