H8S/245x
H8S/242x
Low-Cost H8S 16-bit Microcontrollers
with Zero Wait-State Flash, USB and TFT Drive
Description
The H8S/245x and H8S/242x microcontrollers (MCUs)
offer an extremely low-cost way to generate TFT-LCD
based GUI solutions with medium graphic animation
and a touch screen. No need for higher-frequency,
higher-cost microprocessor (MPU) systems, simply
order our development kit and get started immediately
using the hardware and firmware reference platform.
Key Features
• High performance 33MHz CPU with very deterministic
operation due to zero wait-state Flash memory
• Eight 32-bit general-purpose registers and
hardware multiplier
• ROM-less, 128K, 256K, and 512K embedded full-
speed Flash memory with up to 64K SRAM
• USB-FS 2.0 Device interface w/PHYon H8S/245x
• External DMA (EXDMA) to drive TFT-LCD panels
up to WQVGA (480 x 272) with 16-bit color depth
• 4 channel internal DMA and DTC
• Strong timer resources (2x TPU, TMR, WDT)
• 5x USART (incl ISO7816 and IrDA), 4x IIC, SPI
• 16-channel 10-bit ADC, 2-channel 8-bit DAC
• External CPU Bus interface
• Low-power modes including deep standby
• Choice of 120-pin and 144-pin LQFP packages
• Operating voltage choices of 3.3V and 5V
• 32-bit H8SX upgrade devices (H8SX/166x,
H8SX/165x) with up to 1MB Flash and 50 DMIPS.
These MCUs can can drive up to VGA (640 x 480)
TFT-LCD resolution with 16 bpp color depth

The EXDMA unit becomes the TFT-LCD controller,
requiring only 5% of CPU bandwidth for example
when refreshing a WQVGA TFT-LCD panel at 60Hz,
moving graphic RGB data from external RAM into the
TFT panel. Plenty of CPU bandwidth remains to drive
the remainder of the application and to create
medium animation.
