PIC24FJ256DA210 FAMILY
22.2
The PIC24FJ256DA210 family of devices has two vari-
ants in terms of on-board RAM (24-Kbyte and 96-Kbyte
variants). The 24-Kbyte variant supports monochrome
displays while the 96-Kbyte variant supports Quarter
VGA (QVGA) color displays, up to 256 colors. Support of
higher resolution displays with higher color depth
requirements are available by extending the data space
through external memory. Table 22-1 provides the sum-
mary of image buffer memory requirements of different
display resolutions and color depth requirements.
22.3
Frequency of the Graphics Controller Display Clock
(GCLK) signal is determined by programming the
GCLKDIV bits (CLKDIV2<15:9>). For more informa-
tion, refer to the “PIC24F Family Reference Manual”,
Section 6. “Oscillator” (DS39700).

22.4
The PIC24FJ256DA210 family of devices has variants
with two on-board RAM sizes. These are the 24-Kbyte
and 96-Kbyte variants. These two RAM variants are
further divided in terms of pin counts. The 100-pin
count device will have the EPMP module available for
extending RAM for applications. The 64-pin count
device will not have the EPMP modules. Extending the
RAM size is necessary for applications that require
larger display buffers and work areas. It is recom-
mended that the display buffers and work areas are not
mapped into an area that overlaps the internal RAM
and the external RAM. The external RAM can be
interfaced using the EPMP module. For details, refer to
the “PIC24F Family Reference Manual”, Section 42.
