4) The minimum erasure is 500K times
5) Minimum 10 years data retention
6) SRAM: 256 Bytes(data)+4KBytes(xdata)
2. LCD driver
1) 4x20~8x16 LCD driver
2) 1/3 LCD bias
3) With the low voltage detection interrupt function and LCD voltage adjustment,
it can maintain the stability of LCD display during AC and DC switching
3. LED controller/driver
1) Matrix mode (MX): 8 * 8, 16 pins, up to 64 points
2) Dot matrix mode (DMX): 7 * 8, 6 * 7, 5 * 6, 4 * 5, 8 pins, up to 56 points
4. touch
The touch structure of TM52eF1385/86 is a highly integrated IC that does not require external capacitive components.
42PINs are all TK pins, which is convenient for TK wiring. At the same time,
it can support up to 22-ch capacitive touch keys, and supports internal reference capacitors and automatic touch clock adjustment.
The change is to use the AFTK touch hardware method for touch detection,
and the touch detection speed is very fast
5. Digital Peripherals
1) GPIO has a maximum of 42 bidirectional I/O ports that can be independently controlled
a. All pins have high sink current (60mA @ VCC = 5V, VOL = 0.1VCC)
b. COM pins have high sink current in LED mode (120mA @ VCC = 5V, VOL = 0.1VCC)
2) 9-way 16-bit PWM with cycle adjustment
a. Three 16-bit PWMs with independent period adjustment (PWM0~PWM2)
b. Six 16-bit PWMs with shared period adjustment (PWM30~PWM35)
c.PWM2 with dead zone control
3) Interface:
a. UART0, 8051 standard UART/UART1, only support mode1 and mode3/UART2, only support mode1 and mode3
b. SPI serial port
c.I2C interface (master/slave)
4) Built-in CRC check module
5) 8-bit multiplier and divider (standard 8051), 16-bit multiplier and divider,
32-bit ÷ 16-bit divider
6. Application
TM52eF1385/86 is used in smart home appliances such as rice cookers, coffee
pots, air fryers, air purifiers, and range hoods with LCD/LED displays and touch buttons.
7. Development tools
For TM52eF1385/86, Tenx has designed a convenient USB development tool
HT-Link ICE, which can directly use the original IC (Real chip) for online
debugging, and can directly access memory and set registers, and
provide programs The breakpoint and step (STEP) of debugging can perform functions such as tracking and analyzing data,
which improves the efficiency of program development and debugging
capabilities, and is very suitable for rapid product development.
8. Encapsulation
The packaging is packaged in SOP28, LQFP32 and LQFP44, providing
the best package pins
