A spokeswoman for the company says the Waterloo, Ont.-based company has stopped production on the 16GB Wi-Fi PlayBook.
Remaining supplies at retailers and distributors will be the last quantity.
RIM said it continues to manufacture both the 32GB and 64GB models of the PlayBook.
"We remain committed to the tablet and mobile computing, and will continue to innovate and introduce new products," said Tenille Kennedy, a representative for RIM.
The company has run into trouble trying to sell the device in a market dominated by Apple's iPad and numerous other tablets.
Earlier this year, RIM began selling its PlayBooks at a discount to boost interest.
Shares of RIM ended the day four per cent higher, up 43 cents to $11.04 on the Toronto Stock Exchange.
