Are you sure you want to use a parallell memory. The M27C010 requires 27 I/O:s and the biggest 16F8XX MCU has 33 I/O:s. You will end up with 5 I/O:s left... I'll suggest a serial (SPI/I2C) memory instead. /Patric -----Original Message----- From: Ed Bockhoefer [SMTP:e.bockhoefer@patamerica.com] Sent: den 21 september 2001 20:44 To: PICLIST@MITVMA.MIT.EDU Subject: [PIC]: External EROM Does anyone know of a way (or link to web site) to use an external parallel EPROM with a PIC16F8xx chip? Something like a M27C010 (1meg EPROM) or similar. I want to use a monochrome graphics display with a PIC controller. Unfortunately, I need lots of memory to store the bitmaps for the display. The display will eat up about 5k per picture. -- http://www.piclist.com hint: The PICList is archived three different ways.
