Product details
Overview
XC878CM16FFA5VACXXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the standard 8051 instruction set and executing instructions at two clocks per machine cycle. It integrates 52 KB Flash, 256 B RAM, 3 KB XRAM, and a 10-bit 8-channel ADC. The device features embedded voltage regulation (core at 2.5 V, I/O at 5.0 V), MultiCAN interface, and CCU6 for motor control timing - deployed in automotive body electronics and industrial motor drives.
For engineers reviewing the XC878CM16FFA5VACXXUMA1 datasheet, XC878CM16FFA5VACXXUMA1 pinout, XC878CM16FFA5VACXXUMA1 application, or XC878CM16FFA5VACXXUMA1 equivalent, key selection criteria include Flash memory protection scheme, dual supply rail support (2.5 V core / 5.0 V I/O), CAN 2.0B compliance, and integrated CORDIC coprocessor for real-time trigonometric computation in closed-loop motor control.
Technical Context
The XC878CM16FFA5VACXXUMA1 implements an enhanced 8051-compatible CPU core with two data pointers and zero-wait-state memory access via its two-clock-per-cycle architecture. It supports memory protection through flash bank locking and password-protected register access, enabling secure firmware updates in field-deployed systems.
Its peripheral set includes a MultiCAN controller compliant with CAN 2.0B, a 16-bit CCU6 unit with dead-time insertion and PWM synchronization, and a CORDIC coprocessor optimized for sine/cosine and magnitude/phase calculations - all clocked from a configurable PLL-driven system clock up to 26.7 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC886CM-16FRA5VACXXUMA1 | Same XC800 core, 64 KB Flash, added 12-bit ADC and enhanced CAN FD readiness (pin-compatible but requires updated transceiver). | Supports higher-resolution current sensing and future CAN FD migration paths. | Select when upgrading to CAN FD infrastructure or requiring finer ADC resolution for precision energy metering. |
| TC1762-128F133HRBAKXUMA1 | TriCore 32-bit architecture, 128 KB Flash, no CORDIC, but includes FPU and Ethernet MAC. | Targets complex motion control with multi-axis coordination and networked diagnostics. | Select only when migrating beyond 8-bit performance ceiling - not drop-in compatible due to architecture and toolchain differences. |
Compared with SAF-XC886CM-16FRA5VACXXUMA1, XC878CM16FFA5VACXXUMA1 offers lower cost and proven qualification for body electronics, while TC1762 demands full re-architecture but delivers scalable compute for next-gen distributed control.

FAQ
Does XC878CM16FFA5VACXXUMA1 support JTAG debugging?
Yes, it includes full OCDS (On-Chip Debug Support) compliant with IEEE 1149.1 JTAG, enabling non-intrusive breakpoint setting, register inspection, and flash programming via Infineon's DAS tools. The JTAG ID register is accessible at address 0xE8, and boundary-scan testing is supported per DS V1.5 Section 3.23.
What is the maximum operating temperature range for this part?
XC878CM16FFA5VACXXUMA1 is qualified for industrial temperature range: –40 °C to +125 °C ambient, verified per AEC-Q100 Grade 2 requirements. Thermal derating begins above 105 °C case temperature, and the embedded voltage regulator maintains core stability across this full range.
Can the CORDIC unit operate independently of the CPU core?
No - the CORDIC coprocessor is memory-mapped and controlled via dedicated SFRs (CORDICCON, CORDICIN, CORDICOUT); it executes synchronously with the CPU clock and halts during STOP mode. Its operation is initiated by CPU write to CORDICCON, and completion is signaled via interrupt flag CORDICIF.
Is the 52 KB Flash organized into uniform sectors for selective erasure?
Yes - Flash is divided into 64 sectors of 512 bytes each, allowing sector-level erase without affecting adjacent firmware blocks. Sector lock bits are stored in dedicated Flash protection registers (FLSLOCK, FLSPROG), and unlocking requires a 32-bit password sequence defined in DS Section 3.3.1.
