The VRC VI, often referred to as the VRC6, is a chip made by Konami and used as a memory mapper and audio expander for their Nintendo Entertainment System games. This is the 6th virtual ROM controller Konami made, and it was designed to replace the VRC V. It's model number is 053329. The additional audio capabilities of the chip were only used in three game, and only in their Japanese releases:

In addition to better memory access, the VRC VI grant three additional audio channels, 2 pulse wave channels and a sawtooth channel.

This chip was superseded by the VRC VII.

Pinout

This ASCII art represents the chip's pinout.

(s) means this pin connects to the System
(r) this only connects to the ROM
(w) this is a SRAM/WRAM connection only
AUD : these pass to the resistor network
CHR : these connect to the CHR ROM and/or fami's CHR pins
PRG : these connect to the PRG ROM and/or fami's PRG pins
WRAM : this hooks to the WRAM
CIRAM : the RAM chip which is on the fami board
