1. System Overview
The C8051F52x/F52xA/F53x/F53xA family of devices are fully integrated, low power, mixed-signal system-
on-a-chip MCUs. Highlighted features are listed below. Refer to Table 1.1 for specific product feature
selection.
With
C8051F52x/F52xA/F53x/F53xA devices are truly standalone system-on-a-chip solutions. The Flash mem-
ory is byte writable and can be reprogrammed in-circuit, providing non-volatile data storage, and also
allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and
may individually shut down any or all peripherals for power savings.
The on-chip Silicon Laboratories 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip
resources), full speed, in-circuit debugging using the production MCU installed in the final application. This
debug logic supports inspection and modification of memory and registers, setting breakpoints, single
stepping, run and halt commands. All analog and digital peripherals are fully functional while debugging
using C2. The two C2 interface pins can be shared with user functions, allowing in-system programming
and debugging without occupying package pins.
Each device is specified for 1.8 to 5.25 V operation (supply voltage can be up to 5.25 V using on-chip reg-
ulator) over the automotive temperature range (–40 to +125 °C). The F52x/F52xA is available in the
DFN10 (3 x 3 mm) package. The F53x/F53xA is available in the QFN20 (4 x 4 mm) or the TSSOP20 pack-
age.
High-speed pipelined 8051-compatible microcontroller core (up to 25 MIPS)
In-system, full-speed, non-intrusive debug interface (on-chip)
True 12-bit 200 ksps ADC with analog multiplexer and up to 16 analog inputs
Precision programmable 24.5 MHz internal oscillator that is within ±0.5% across the temperature range
and for VDD voltages greater than or equal to the on-chip voltage regulator minimum output at the low
setting. The oscillator is within +1.0% for VDD voltages below this minimum output setting.
Up to 7680 bytes of on-chip Flash memory
256 bytes of on-chip RAM
Enhanced UART, and SPI serial interfaces implemented in hardware
LIN 2.1 peripheral (fully backwards compatible, master and slave modes)
