C62x
device compatibility
The TMS320C6202, C6202B, C6203B, C6203C, and C6204 devices are pin-compatible; thus, making new
system designs easier and providing faster time to market. The following list summarizes the C62x
DSP
device characteristic differences:
D Core Supply Voltage (1.8 V versus 1.5 V versus 1.2 V)
The C6202 device core supply voltage is 1.8 V while the C6202B, C6203B, C6204 devices have core supply
voltages of 1.5 V and the C6203C device has a core supply voltage of 1.2 V.
D PLL Options Availability
Table 1 identifies the available PLL multiply factors [e.g., CLKIN x1 (PLL bypassed), x4, etc.] for each of the
C62x
DSP devices. For additional details on the PLL clock module and specific options for the
C6203B/03C devices, see the Clock PLL section of this data sheet.
For additional details on the PLL clock module and specific options for the C6202/02B devices, see the
Clock PLL section of the TMS320C6202, TMS320C6202B Fixed-Point Digital Signal Processors data sheet
(literature number SPRS104).
And for additional details on the PLL clock module and specific options for the C6204 device, see the Clock
PLL section of the TMS320C6204 Fixed-Point Digital Signal Processor data sheet (literature number
SPRS152).
D On-Chip Memory Size
The C6202/02B, C6203B/03C, and C6204 devices have different on-chip program memory and data
memory sizes (see Table 1).
D McBSPs
The C6202, C6202B, C6203B, and C6203C devices have three McBSPs while the C6204 device has two
McBSPs on-chip.
For a more detailed discussion on migration concerns, and similarities/differences between the C6202,
C6202B, C6203B, C6203C, and C6204 devices, see the How to Begin Development and Migrate Across the
TMS320C6202/6202B/6203B/6204 DSPs application report (literature number SPRA603).
