The C515C is an enhanced, upgraded version of the SAB 80C515A 8-bit microcontroller which
additionally provides a full CAN interface, a SPI compatible synchronous serial interface, extended
power save provisions, additional on-chip RAM, 64K of on-chip program memory, two new external
interrupts and RFI related improvements. With a maximum external clock rate of 10 MHz it achieves
a 600 ns instruction cycle time (1
µ
s at 6 MHz).
The C515C-8R contains a non-volatile 64k byte read-only program memory. The C515C-L is
identical to the C515C-8R, except that it lacks the on-chip program memory The C515C-8E is the
OTP version in the C515C microcontroller with an on-chip 64k byte one-time programmable (OTP)
program memory. The C515C is mounted in a P-MQFP-80 package.
If compared to the C515C-8R and C515C-L, the C515C-8E OTP version additionally provides two
features:
– the wake-up from software power down mode can, additionally to the external pin P3.2/INT0
wake-up capability, also be triggered alternatively by a second pin P4.7/RXDC.
– for power consumption reasons the on-chip CAN controller can be switched off.
Note:

(SAH-C515C-LM and
SAH-C515C-8RM) are available on request. The ordering number of ROM types (DXXXX
extensions) is defined after program release (verification) of the customer.
